David emailed me to ask what the below object is. I have no idea, although the suggestion that it’s a cartridge delinker sounds plausible.

I believe it is a military accessory and I would like some help to identify what it is. Attached is a picture, there is a stamp on the side that says “8D/2538″ with a crown and “M” below that, and a circle below that with “R G 31″ inside the circle. It appears to be made from brass. Someone suggested it is possibly a delinker to remove shells from a machine gun belt.

Anyone know?
