Bofors 37mm Automatic Casing? Please help me identify this item

[M8owner]

I picked this up in an antique store. It looks like a scaled down Bofors 40mm, but it is definitely 37mm.

This is probably a 37x252mmR Russian M1939 AAA cartridge case. Good find!

This is definitely Russian. I have seen a lot of these cases with this exact same headstamp on the surplus market.

I have one of these as well. This is how the markings were identified to me: cannot confirm the accuracy as these came from a forum posting.

32-74: Lot Number - Year

K : Case made from silicon brass

184-И : Manufacturer (Zelenodolsk Factory Associates, Zelenodolsk, USSR) - "Military control stamp"

I hate to admit that I thought it was a Bofors 37mm AT gun casing when I bought it. I do not collect AAA stuff. Anyone want to add this to their collection?
