Bofors Gun Open Closed Indicator.
Took me a few years to understand it, I was looking too hard.. why was it not moving as gun was cocked!! Now i know.. its a manual lever operated by hand!! not by the gun mechanism..
This manual also answered another question, My firing pins have TWO springs to operate them behind the striker. One big spring and a smaller one fits in the middle of the big spring.. This is normal and correct. double spring for maximum thrust. I didnt know why it has two springs, I have five of these guns and all are the same.
