Suppressed OSS M3 Grease Gun and Bushmaster Booby Trap Trigger
Vložit

- Today, we have a chance to take a look at a suppressed M3 "Grease Gun", as purchased and issued by the Office of Strategic Services (the OSS; predecessor to the CIA). Thanks to its readily removable barrel, the M3 (and M3A1) submachine gun was an easy gun to adapt to use with a suppressor (or as it was called at the time, a silencer). During World War 2, such a unit was developed for clandestine use by OSS and British SOE agents in occupied Europe, and they would see use for many decades in all manner of conflicts.
The suppressor itself is quite different than modern designs, being a two-part device using tight wire mesh instead of baffles. The barrel itself is heavily perforated, and extends only through the large diameter section of the suppressor. Around it is wrapped a large roll of wire mesh, which acts as an expansion chamber to slow down the exit of gas from the muzzle. The smaller front section of the unit is filled with small discs of the same wire mesh, similar to wipes but made of mesh.
Allegedly, the suppressor was effective enough to reduce the noise of the gunshots below the level of the action cycling, which is all that one can reasonable want from a suppressor. This particular example has an excellent provenance, having been provided by OSS to a European resistance fighter for a specific mission right at the end of WW2.
In addition, we also have a piece of the OSS sneaky tricks catalog to see. Specifically, a "Bushmaster" remote trigger mechanism to allow the M3 (silenced or otherwise) to be made into an autonomous booby trap in conjunction with a time delay, tripwire, or other triggering device.
Many thanks to the anonymous collector who let me take a look at this piece and bring you a video on it!

i love the simplicity of older guns. “yeah man its just a pipe that shoots metal out of it i dont know what else you want from me”
@@justforever96 thats a really long drawn out way of saying older guns are awesome
went from the finally machine tooled Thompson submachinegun to a stamped welded pipe that shoots .45 aka M3
I was baffled by that mesh.
Goat Lord You must be nothing but hot air then! 🤣
Goat Lord well, that joke went down the tubes fast. Now, the silence is deafening.
Oh you!
Ian @ 7:56: "Now this is a really cool piece of little OSS evil _triggery_"
pft, low hanging fruit...
be a giraffe and stretch a little ..."I was baffled about such early suppressors but then he took it apart and I saw how well the technology meshed with others of the time"...
But don't let this distract you from the fact booby trap spelled backwards is party boob.
I love you.

You deserve 1 boob.

Why TF is CZcams censoring out the suppressor on an antique firearm that likely most people do not and will not ever possess 😂
Apparently, YT think that threading something in the front of the barrel is "modifying" a gun, that they included as a "how to make a homemade gun"
its not CZcams, Ian himself had to blur every clip that shows him attaching a suppressor because CZcams was cracking down on that. Doesnt apply anymore though
I "inherited" one these M-3A1s in early 1973 when I was on a "plain clothes" TDY assignment in Viet Nam before the Paris accords went into effect. I only had a couple of opportunities to fire it at the range and once when we were destroying assets and property that had to be left behind. There were a couple of issues with the original guns. The wire mesh tended to break down during use. The silencers became fairly ineffective after only a short period and needed to rebuilt depending on the use. This was due to the heat and carbon build up that ruined those screens. Also, the larger section of the silencer (the section closest to the receiver) became VERY hot and mine came with a wool padded, leather covered, laced on wrap so the shooter could hold that section during firing. But, even with that it got very uncomfortable to shoot. Not a fun gun to shoot beyond a magazine or two. Heaven help you if you lost that pad. BTW, Ian talked about the guide rod for inserting the screens... Well that was when they were originally issued. Didn't take long for that rod to get lost along with any inventory of those special screens. And, they were regular steel, not stainless so they rusted out just about as fast as they were shot out!!!
M3A1 version could not take a suppressor, you must have had the M3
@@wernesgruder1 I don't understand. . .are not the M3 and M3A1 barrel interchangeable, Don't they both accept the 9mm conversion kits ? Why would it not mount on the other gun . . .
@@wernesgruder1 eh what are you talking about. Not only are you incorrect but it was clearly stated in the video that the barrels are interchangeable between the m3 and the m3a1. There was only minor differences between the 2 only the way of charging the gun and a magazine loader on the rear. If you don’t really know what you’re talking about just don’t say anything, you just end up embarrassing yourself…
@@wernesgruder1 yes they could, theres literally documented pictures of OSS M3A1s with the exact same suppressor, along with the leather covered wool pad DoneThat mentions
@@wernesgruder1
Yep they could, I know because I have one 😊
Just imagine that German politician walking to his hotel room, triggering that booby trap with the door. Sounds like a 70's movie. :o
like a 70's movie? ... or a cartoon frog dancing on a 1940's typewriter ...
Or maybe like that one scene from home alone. 😪
You mean a snuke..
Very Tarantino.
Players of _Fallout 3_ and _Fallout New Vegas_ will be uncomfortably familiar with the concept of the Bushmaster device. Where do the Raiders get all those combat shotguns?
And Fallout 4. I'm careful not to stand directly in front of doors as I open them, but the *blam* of a trap going off is just a sigh and facepalm moment. Damn raiders.
Now just add a ww2 red dot and laser sight and you've got call of duty ww2 multiplayer
123 456 No, you'd have a gun. Add two or more preteens, remove all intelligent thought, NOW you have a COD multiplayer...
No, I said "remove all intelligent thought" ;)

123 456 no, that's bf1. Ww2 era equipment would be too old for cod, they would have plasma ak's (painted neon purple, only in supply drops)
BF1 : were making a game with lots of historical realism

good work game devs really focused on the reality of war
I like how the baffle mesh screens match the table cloth.
Obviously designed to avoid casual detection by enemy forces!
Suppose his wife knows he uses her table cloth to disassemble firearms?
Nah. Surely not.
A great video, but an aside - how fucking stupid is youtube for making you censor just the act of putting a suppressor on
Hey! It's "community standards"! Whose "community standards"? Certainly not those of the majority of Americans (nor, probably of the rest of the world).
I will have to create a patreon account, because of this channel and others. Ian is so active lately, and his content so rich, that it is impossible to imagine myself as a "gun guy" without at least having some memory of a Forgotten Weapons video, serious gun-lore, serious tecnical stuff, serious fun... THANK YOU!
Thanks!

As an FMF corpsman with Marine Recon, I carried an M3A1. Mine must have been a later model. It didn't have a rod sticking out to cock it. It had a finger hole in the bolt you pulled it back with. Rust was a problem. Glad I didn't have to clean that suppressor.
Someone realized the cocking lever was unnecessary. Later versions had a simple hole in the bolt, to stick your finger into.

You dont know how true this is in 2020 lol
@@IIDEADBIRDII exactly what I was thinking
Silencer tax+SBR tax+machine gun tax=too much regulated fun
On the one hand, once it's a registered machine gun the barrel length is no longer regulated. Also, where this gun is located, the NFA does not apply.
+Forgotten Weapons Where I live (Australia) the NFA means something worse 😂
> Also, where this gun is located, the NFA does not apply.
Where is that?
Probably in France or the UK.
even thats pretty reasonable for access to an automatic weapon, but is it a similar process to own a regular gun? like say you wanted a bolt action .22lr, would you require a special reason? (part of a gun club that does competitions)
Thanks for all your hard work Ian. Really appreciate the content.
I wish someone would airdrop me the that M3 _and_ a welrod lol
Rather a FG42, or another rare, but cool gun.
You need Gun Santa, but only if you have been Good.
become an important resistance fighter in a major conflict, and you might get your wish
+Glam Stachee that escalated quickly
Heinrich Muller A DeLisle as well?
Luckiest guy ever to just get a free suppressed M3 and Welrod, and then the government is like, "Yeah, just keep that."
not ever but lucky sure
mate youre telling me i can go get a roll of fly screen and make a suppressor from aluminum tubing sounds like fun
sadly not weird enough
a car oil filter damp with oil, just stuck to the muzzle is also a effective suppressor
Yes, in classic BATFE fashion, they said it was fine because it would not fit a real firearm, then said nevermind we are regulating it all.
from what i understand with air guns and paintball is its ok to do supressors now but they must be permanantly affixed, for example gamo sells some supressed 22 caliber air rifles but the supressor is threaded to the barrel, welded, and the whole thing is coated in a polymer sleve
@@therideneverends1697 ...fucking killjoys.
These guns are prominently featured in an Australian WWII movie called "Attack Force Z," which starred a very young Mel Gibson.
When I was a boy I idolized my grandpa who was a WWII tanker with the 20th AD. I don’t know where I got the idea, maybe a comic book, but I built my own replica Greasegun, or as best a 10 year old could do. I took a regular caulk gun, cut some pieces of wood to shape the pistol grip and magazine then used some scrap sheet metal and a pipe for the barrel. I painted the whole thing flat black and showed my grandpa, he was impressed. Later on I found out the M3 was made in my hometown. I know it sounds funny but some people think of this SMG as a weapon but for me it’s a cherished childhood memory.
At the end of the day there is nothing that brings me more joy than watching your informative and well thought out videos.
keep it up Ian!
I love the simplicity of the triggering device. To think, there was an international standard for booby trap trigger devices.
Now this one was actually dropped once and never fired.
Guess that drop safety's doing its job, eh?
ToastyMozart Yee
is it an Italian gun then
Lol too funny
NRSS Cheatham more french i would say
Thank you for posting this. My great-uncle was in the OSS during WW2. Neat seeing stuff he might have used.
The m3 is easily my favorite SMG. So sensible. Thanx for showing off this rare mod set. I used to love the dk spy books as a kid .
I love these shows. Short but very informative. Thank you.
When I saw the trip wire attachment, it reminded me of a gun or bub-bey trap called the Early morning wake up call. It was made by a company of the same name and was stamped EMWUC. People back in the stage coach days when traveling would have to stop at night and sleep. This device would screw into the door trim of your room and flip in front of the door so if someone entered it would fire. It was of small caliber so probley didn't kill the person instancey but the lead poison in the end was a very pain full death. This tells me two things. 1 With a name of EMWAC people back then had a sence of humor, and 2 That's a forgotten weapon. Love this channel.
You have outdone yourself again, Ian. I'd read about these in OSS stories about the Jedburgh teams but never thought I'd get to see one of them? Thanks!
Very interesting. Heard of these but never seen one. The suppressor design is genius in its simplicity. Easy to find spare parts too. That trigger device is slick- especially mating to standard gear like the M1 pull firing device ("old reliable" as most EOD guys call it). Tripping that would definitely ruin your day as u went through a door. Great video as always. Thank you
Ah yes a bullet hose 🧐 what a pristine specimen of such simplistic design.
that suppressor is amazingly simple. great video as always
This was one of your best presentations yet.
I'd love to see an accuracy, control, and comfort test between that old grease gun and more modern submachine guns. Excellent video Ian, love this channel.
It's not even close. They've come so far it's mind blowing.
The chance to see stuff like this is why I love this channel
For those that wonder how a chemical timer works:
no, it's not a chemical reaction that blows up eventually, or anything that fancy. It's far simpler: imagine a spring held back by a wire and once something breaks the glass vial an acid is released, slowly dissolving the wire. AFAIK, there were timers ranging from 5min to 48h.
I wish, they built them in all aerial bombs. They did it in some, but we still got F-loads of unexploded bombs littering the earth, slowly corroding.
well that assumes the mechanism remains functional after ... you know... dropped from the air and crashing into the ground at terminal velocity.
the problem with unexploded bombs after all is that their fuse failed to detonate the bomb and if they had self destruct mechanism (a lot of bombs do, some on purpose as a terror weapon as it makes their disposal difficult) then it may have failed as well,
but the chemical timer is for all intent and purpose just another fuse really...
so in order for it to work on aerial bomb to prevent a bomb from not exploding after the main fuse failed, then it must somehow be made stronger than the actual fuse the bomb had...
which then begs the question of why not just make the original fuse for the bomb better and prevent it from failing to explode in the first place
Many bombs had more than one fuse, after they discovered that up to 20% failed to detonate. Using a chemical timer has two advantages:
1) it's simple. If the delay fails, it still detonates.
2) the delay makes the bomb unpredictable to the enemy. They thus can't just come back after the other bombs exploded.
yes we know that, but the question is... if the bomb suffer damage to such extent that the primary and secondary fuse failed, then will the chemical timer remain functional for it to matter?
after all... while the mechanism in it usually is simple, they are not necessarily damage proof regardless... and the primary fuse in bombs are not exactly made of flimsy construction in the 1st place, and so does the secondary timer usually built on them (which i already mentioned)
so the chemical timer needs to be sufficiently robust and durable enough to actually withstand whatever damaged the bomb to the point that both the other fuse failed...
Iono Sama If the wire ruptures prematurely, it detonates on impact. All that needs to withstand the impact is the tube containing spring and striker.
which is great, but the thing is... a number of the fuse they use on the aerial bombs... technically are supposed to work even if just the percussion plunger and detonator remains intact... those work on impact detonation as well
if even they can fail either from damage or any other reason, then what guarantee do we have that the striker in the chemical timer remains functional if subjected to that kind of damage? Other than of course... placing it in different location, and praying that it's enough to help spare the chemical timer critical component.
i mean don't get me wrong, more backup self destruct mechanism is fine...
but we're basically just layering more and more fuse onto the same bomb in order to hope that at least one of them worked... so we're just reducing the chance the bomb failed to explode completely by putting more redundancy in fuse.
that device looks like it could have been assembled out of washing machine parts which it probably was knowing the oss :P
DeanmC261993 Which is the reason I like it so much!
This type of design could make a comeback as a very inexpensive home build.
If the HPA passes it would be pretty popular for pistol caliber carbines.
no I mean the booby trap device :P
DeanmC261993 I'm not so sure. That mesh looks like it would be really annoying to clean. A cheap home build could easily use washers and other hardware odds and ends for baffles.
that's also kind of the point, if you got caught by someone with that in your pocket you might be okay. If you got caught with something that screamed explosives fuse device trap, etc etc you might have some explaining to do!
To clean the meshes you could easily just tie them together and toss them in with the laundry or something.
I was gonna say "dishwasher" but I don't know if those existed in the 1940s.
This is perhaps the coolest looking firearm I've personally seen.
I think this is one of the coolest videos I've ever seen from you such a history on such a unique gun truly amazing
thank you, Ian. I love integrally suppressed weapons, especially submachineguns.
Great Video Ian. Thanks. Love the segue into the booby trap mechanism.
As far as sound I have heard that it's like a baseball bat hitting a wet sandbag.
JKCDLT That would sound cool
Tfw fell asleep videos ago listening to the liberator. What an awesome channel. Thanks Ian!
Damn... What a mesh
This peice of kit is so badass. The mission, even more badass
Awesome video, Ian! I love the sneaky stuff!
Ian, thanks very much. I had heard of these guns, usually as a sidenote to material about the history of the M3. This is the first time I have seen the innnards exposed to see what really happens. Pretty cool engineering. Always funny to see the difference between the Hollywood versions of a "silencer" versus a real suppressor. Keep up the good work.
Excellent presentation Ian. I always loved the M3 and read that when this gun was fired with the suppressor on , the bolt slapping back and forth was more prominent than the muzzle report.
Got you already covered on patreon, I find myself looking forward everyday for my faithful dose of gun Jesus wisdom, thanks for your passionate pursuit of what we gun geeks really enjoy!
I have a retired Special Forces buddy who lives in Thailand that has one of these. It's his favorite goto weapon.
Another great video Ian. Thanks!
very impressive history, and description. Thank you.
I've learned so much. From all your videos...
Concise courteous correct & cool
Thanks, Ian. I read about these weapons (in some fiction about a Jedburgh team) and have always wanted to see this one.
Great video once again. I love Ians (Iains??) technical breakdowns along with the history.
One of the greatest warriors in Vietnam chose this as his favorite weapon (along with a sawed off shotgun, 9mm uzi, numerous grenades, scuba knife, and 5 or 6 pistols). JERRY "MAD DOG" SHRIVER was killed (mia) charging a machine gun post. He was the real life Rambo.
There's a few pictures of MACV SOG operators carrying this exact setup.
I really love that painting...
Really cool find Ian, especially with the booby trap parts
My great grandfather used an M3A1 Grease Gun during ww2.(He alsoused a Lee Enfield and M1911A1pistol)
Just want to say, I love your channel so much! ❤️
Thanks for going to peace on that particular grease gun, very cool
That is so pathetic that you cannot show connecting or removing a suppressor from a firearm...yes CZcams...pathetic... 🤬
Nice video! Keep it up!
The point about wire mesh in supressor, is mainly of its great surface area, that surface cools down hot gases, wich helps a lot in reducing volume of gases. I think that is the main reason why they use a wire mesh. And that way to supress is working VERY well :)
what a gem... and quite an interesting history
badd ass!
thank you for this detailed blessing of the suppressed grease gun. THANKYOU.
Did this… get edited to comply with the new YT guidelines? Holy crap. Where are us regular viewers going to find an M3 grease gun and an OSS suppressor to swap out?
Found you on accident and I love your videos. Just about any gun I can think of, you seem to have done a video. You also linked me to TFB and Indy Neidell. Thank you and keep up the good work.
new insight on an old favorite
I love the M3 Grease Gun! Happy New Year, Ian.
Ian, you make great vids! 👍Greetings from Holland
This is my favourite video of yours I've seen, I'm really in to WWII weapons.
Nice one✌️
Never knew these existed, awesome video!
One of the best looking guns from the mid century if you ask me
wow, very cool. Great one Ian.
No joke that looks very easy to put together.
Very cool piece, never seen one before.
ahh it's interesting to see history from the perspective of firearms and devices to use firearms in a creative and interesting way...
What a total PITA it must be to go back and edit out all the youtube prohibition silliness. Good on ya for keeping these videos available here, though.
I get that vibe I used to get when I would hear the Modern Marvels or Tales of the Gun intro and I knew something good was going to be on.
This was fascinating. Thanks.
Ian. I read a book from the first Delta Force operational detachment in 1977. They used these and loved them. He said snapping your fingers was louder then the guns report.
Well done Ian!
Hi Ian,
I own a W.Griffiths shotgun made in Manchester, England around the 1870s.
I've done a little research on it but have come up fairly dry.
If you're ever in the UK you're welcome to come and have a look at it.
Hey this was cool! 1st one I have seen.
Very nice. Excellent condition.
the Grease Gun just makes me happy
Ian finds the coolest things!
Hi Ian!
That gun looks fantastic
beautiful piece of history
Pretty sweet bit of kit. Want one.
Amazing state of gun !
As a matter of fact, I saw this model in an article of an Italian Military review in the 1980s that described the Italian Navy Special Forces (Comsubin) arsenal. It was described as being very popular among the teams.
It was nice to see how the parts...
Mesh together? Thanks again gun Jesus
Your historical videos are the best! I always feel like I have just watched an expert at work. We had the M3's in Vietnam in our cavalry unit.
1969-70 with 2-1 Cavalry.
There's the armored cavalry (scouting and security forces equipped with armored fighting vehicles) and the air cavalry (airmobile assault infantry, typically transported by helicopters).
ZGryphon There's 1 unit of classical Cavalry still left
The scariest job I had in the National Guard was being the NCOIC of a range training noobs to use M3s. The slow rate of fire and controlability were real pluses forva beginning shooter.
How to know if someone is a Vietnam vet: wait five minutes and they'll mention it. Or just look at the hat.
So interesting. I loved learning about the booby trap mechanism.
Thanks for sharing!
The M3 is one of my favorite guns. I know I'll never afford an original for my collection so I bought a Valkyrie arms M3 and I love that thing. It looks weird with a 16" barrel but it's a hoot to shoot!
Maybe you could put a dummy suppressor cover over the barrel?
Something to make it look like this OSS suppressor.
I really hate the SBR and SBS bullshit.
Having to go 16 or 18 inches ruins the lines and functionality of a lot of carbines.
@@tylerwilliams6022 If I had a spare barrel I would. But I haven't been able to get a hold of Val to see if she can make me one.
After seeing the screen material I must say that substituting wave springs/washers would work much better and would be better on the nerves.
Was hoping to "HEAR" it..... :(
Thanks for sharing! Cool story!
