I am hoping that there is someone out there that could help me or point me in the right direction of someone who would know about historical Marine Corps issued gear.

I have a brass lock that I found in a flea market in Belgium a number of years ago and want to see what kind of info I can get on it. It looks like it would go on a footlocker and is made of brass, and has the USMC stamped on it. It has a pretty unique style of opening and closing.

Any help would be appreciated.
