None of those numbers match serial numbers given in my reference. Are you sure you have read them and posted them correctly? Hammerless damascus barrel shotguns were made in two groups from 1884 to 1886 and 1886 to 1890. We caution shooter to be careful about shooting old damascus barreled shotguns for several reasons.We can't see the gun to determine its condition, the barrels may have rust pits almost all the way through the barrel walls. These old guns were used hard and received little maintenance and care. There are cheap made guns out there that were unsafe to shoot using almost any ammunition. Usually these are inexpensive poorly made Belgian made guns made back in the early 20th century often referred to a Just Another Belgian Clunker (JABC). Damascus barreled guns were not designed or made for modern ammunition loaded with high pressure smokeless powder, steel shot or slugs. Given the American propensity for wanting more powerful ammunition somewhere, sometime, some damn fool is going to stuff a 3 inch magnum in one of these old guns (it can be done), cock the hammers and pull the trigger. If when various pieces take off for parts unknown and if he is still standing, has the normal number of fingers and eyes, we don't want him coming back to us and say "You didn't tell me that wasn't safe!"
