A Rare 25-Bore Flintlock 1756 Pattern Land Service Pistol
By Grice, Dated 1759. With plain russet barrel and tang, border engraved rounded lock (top jaw and screw replaced) with 'GR' crowned and signed above the date across the tail, figured moulded full stock (old bruising) with shallow apron around the tang, and stamped with obsolete mark on the back of the butt, regulation brass mounts including shaped rounded side-plate, spurred pommel and shaped vacant escutcheon, brass ramrod-pipes, and original brass-tipped ramrod, indistinct King's proof mark and sold out of service mark.

This is probably one of the best examples I have encountered. Completely untouched/cleaned.
