devincu Posted April 8, 2020 Share #1 Posted April 8, 2020 I picked these up at an auction a few years ago because they were cheap, and I stashed them away until tonight as I was doing some cleaning I came across them. Someone told me that they thought these are a bolt assembly for a 20MM Machine Gun / Anti Aircraft Gun used by the US Navy Oerlikon Mark II. I thought if I put posted them here on the forum that someone would know? Thanks, Link to comment Share on other sites More sharing options...

SubgunFun Posted April 8, 2020 Share #6 Posted April 8, 2020 Wow. Those sure are beefy bolts! I'm sure someone will have the research done and get you an answer soon. The device with the red paint on it is an M1 Carbine blank firing attachment (BFA). Not sure if you knew that and had it in the photo for size comparison.

Thank you, I had no idea about the Carbine blank firing attachment. It was in with the other pieces when I got them so at least one mystery solved!
