OK so I have two boxes with these parts in them and I think they are 20mm pom pom parts but if you know what they are I am curious. Certainly 20mm Navy with the rebated rim but not sure which weapon they are for.

I don't believe they are for the Oerlikon. The Air Force, and the Navy had some odd 20mm guns like the ones in the early jets and in B-29's.

Thanks Glass I just found more 20mm parts I have to figure out because I have no clue what they are for.

Third attempt writing this post, lol

Searched on my phone for about 30 minutes with no luck, gave up and went through my recent photos and realized.. are you sure it's a 20mm? I'm 90% sure it's actually KPV parts.

Breech setup looks identical

And it has the threads for the barrel end
