I don't have pictures, but came across an original side by side signed W Allen on the rib between the barrels. The locks, trigger guard, butt plate, and entry thimble have all been stripped off the gun, but from the inletting, they were all pretty fancy and the trigger guard looked to be about 9 or 10 inches long. It appears to have been an original flint converted to percussion, but the drums are also missing. The butt is wide and the shotgun is fairly heavy, but in good shape overall with the exception of all the missing parts. Does anyone have any information on a W Allen and what time period he might have built guns? Thanks for any information you can give.
