Any info on 16 ga

[Bill Murphy]

USC is United States Cartridge Company. Your gun was probably an ammunition test gun. A book was published years ago about the collection of the USC Company. It is hard to find, but may picture this gun. Actually, not too hard a book to find. Amazon lists paperback reprint and 1950 hardcover for sale, both under ten bucks. A PGCA letter may connect the gun to USC when it was first sold. This would be a great collectors find. Tell us where you're located and maybe we can suggest someone to inspect your new gun.

You should look at a PP article I wrote that features USC guns including this one.
Of course you need to join PGCA to get the PP articles. Get going!
Bill must have forgotten.
