Mystery SMG bolt? Ingram M-6?

[goldidig]

Guys, I am trying to ID a mystery SMG bolt I found in one of my boxes of goodies I had stashed away. We pulled this from an unissued gun about 30 years ago that we broke up for parts for a customer and my memory is telling me it was a .45 Ingram M-6 but I could be wrong. It is DEFINITELY a .45 ACP. I don't have it in any of my schematics and I was wondering if any of you lads can ID it for certain.

Probably right about the M6. The only other .45 acp smgs I know of with a round bolt are the M3 & Reising M50 series.

Yup.

Neat find!

Yes, that as a rare piece for sure. It's hard to believe we even parted that gun out back then. That was back in the good 'Ol days though. I am going to list that bolt in the EE soon guys. What do you think is a fair price I should ask for it. I don't want to hose anyone, but I don't want to sell myself short either.
