These are 20 port at a lower RPM, and are driven by a very large electric motor. I'm not sure the exact number of units left remaining, but there definitely aren't a lot of them left due to their age, especially active units. They were first made in the early-mid 1910s (Was patented in 1915, but some believe they were produced as early as 1912), and the company went out of business LONG ago and these are certainly no longer made. I don't work at a siren company, but this information comes from a reliable source on the forums.
This is definitely a throwback to last year when we first met each other. Only this time we got the siren exactly the way we wanted to.
Wow! I wish that they would be still in use, and hungary to have them, and have them active
These things look and sounds massive!

When I was about to see a Denver duplex siren video I thought they didn’t exist but when I saw one go off I didn’t know these exist
