And again, thank you for sharing all these!
It is impossible to find all these things without other people (like you)!
What is the gun shown in the photo in the document?
It is not a Bofors automatic cannon. Were there any manually loaded guns made in this calibre, or is it a stock photo of something else?
It also refers to this calibre as semi-fixed with adjustable propelling charge. The photo shows the projectiles crimped into the cases. I have never read about the existence of semi-fixed Bofors ammunition before.
