I picked up a neat one at this weekend's Reno Show. I know only that it is pre-1902. The serial number is 8786. Box lock, A&D, double Purdey Underbite, dolls head with bite. Virtually no wear. Very nice wood. Very nice scroll engraving. Nice dimensions. Scroll lettered on under rib "Chambered for 2 3/4" Cartridge". I don't see many this clean this old. I am guessing late 1880's but anyone know for sure?
