English Flintlock Pocket Pistol Circa 1790

This fine antique flintlock pocket brass framed pistol is engraved on both sides with a Trophy-of-arms and is signed "Conway, Manchester." The walnut grips are finely checkered. The overall length is 4 3/4". It comes complete with what I believe is the original book used to conceal the weapon during travel. It is leather bound and dated 1768. It has been repaired and the top board is somewhat lose.
