The Laminated Steel and Choke Bored marks are often found on utility guns imported from Belgium c. 1900, but Walters and Son does not show up in my list of about 200 retailer/trade names. I can't find much on any gun-making Walters. An A. Walters is listed in New York (1922 and 1925) and also in Milbury, MA, (1836-37). Same person or 2 or 3 different people?? George Walters worked in London, c. 1836-1857. If you have a breech-loading gun, it could be by George. The dates listed for A. Walters were all too early, but he (they) may have still been in business when cartridge arms came along in the 1850's. Are there any proof marks that might help identify the origin? An "ELG*" in an oval (with or w/o a crown above) or the "Peron" (looks like the Washington Monument in D.C.) would confirm Belgian manufacture. Other crowned initials could point us to other countries of origin, possibly increasing the probability that it might be by George Walters.
