Triumph bonnies 1st and last 650

I have a 1959 bonnie I picked up as a ratty chopper. I found all the things to make it right as it is a matching# bike. Not perfect. My stuff never is. Point is this is the first yr 650 bonnie.ie twin carb. The other a 1974 matching # bonnie is only a few away from the very last 650 bonnie, this is a September and the last was in October '74. I have ridden this bike a lot and it shows it. Been a very good bike.
