I'm new to this forum, recently purchased a contemporary rifle at an estate sale with the initials ALM on the barrel in script. I'd like to find out more information on the maker. The lock is a H W Robbins lock dated 8/14/71 on the inside. I've found the references to that lock, sounds mechanically very good. It's a nice gun, with an ornate pierced brass eagle patchbox, total of 12 silver inlays, and some butt carving. 38.5 inch barrel, 40 cal, curly maple. I will post pictures if I can figure out how to do that.
