Lots of guys marked one or two guns, some a few more, and some are worth researching. Here's a clue of my own hallmarks.

These are the four hallmarks I’ve used since about 1977 at Trinidad as struck in sheet lead. From left, a 1/8” x 3/16" commercial stamp with inset letters, next three hand-cut dies with raised letters. The two middle mostly on muzzleloading guns and the one at right since about 1993 and in current use measuring 1/8” x ¼”. The first struck in steel or silver, the middle in silver or gold and the last only in 24kt.

Most shotguns marked behind trigger. Most rifles in octagon barrel, some on action.


M/L guns on barrel breech. I still use the first stamp on benchmade tools and just a couple of shotguns were marked something like this.



I always do close-ups photos of signed guns that I photograph. but I have some good friend, with long careers doing great work who seldom mark, hide of disguise, or haphazardly sign custom work!!??!!



Hopefully all of this will make it a bit easier for future MP and Jerry types!
