The original pre-1399 and representing a step in the evolution of guns. Just over 12” length, in three stages. Central octagonal breech with touch hole, Tapered flared muzzle barrel and octagonal tail piece socketed for a tiller or stock. Bored authentically to the original with a step from the barrel bore to the reduce diameter powder chamber. The underside with K al mm 16, 8.18g SP 28gBL followed by a series of proofs (?), B020 and KOPIE. Wonderful age character and indistinguishable from the original but for the markings. Age unknown.
