I have been collecting double guns for over 25 years but have never seen one of these. Picked this up the other day for a song and a dance. Beautiful 12 gauge gun with a narrow petite frame, 30" damascus barrels, snap action Daws patent opening lever, and back action locks. Maker's name on locks and barrels is H. Thompson & Co. I know that he made muzzle loaders. The part I can't figure out is "Ansell & Co. patent" on the Frame and on the top tang between the hammers. Can anyone shed any light on this patent? Thanks!
