Spanish Double Barrel Pinfire. Approximately .35 caliber Pinfire. Bore has good rifling with some corrosion. This is a tip-up folding triggers barrel pistol (release button on left side of frame). No makers name but well-made pistol. Barrel length is 3 ¾". Overall length is 7". Grips are fluted and pistol has an iron butt cap also fluted to match the wood flutes. Frame has a checker board crisscross pattern with what appears to be very tiny silver tacks in each square. We know this to be Spanish because we have handled many full-size versions of similar pistols.
