A Fine Antique English Silver Mounted Queen Anne Style Turn-Off Cannon Barrel Flintlock Pistol by ISAAC SMITH, LONDON, circa. 1727-1756.  5", .58 caliber smooth-bore steel turn-off cannon muzzle barrel numbered "1" (most likely one of a pair).  The pistol is in its original flintlock configuration.  The all steel frame has fine decorative engraving on the top of the breech and "LONDON" (a bit worn in areas) and "ISAAC SMITH" just below the frizzen spring on the right side.  The bottom of the breech is struck with (2) oval "PROOF" and "VIEW" marks just in front of the trigger guard as well as a "CROWN" over "F" (Foreigner's mark).  Engraved steel trigger guard is the safety when pushed forward in the half cock position.  The wood grip stock has a decorative raised foliage and scallop shell design around the barrel tang and is solid with light scratches and dings from years of handling.  The sides of the grip stock has inlaid silver strength supports.  Beautiful classic high-relief Georg
