The multi-stage barrel has London commercial proof marks and flares to around 1 1/4 inches at the muzzle. The main bore is closer to 10 bore. The rounded lock has the Georgian cipher at the center, a smaller crown mark below the pan, and "TOWER/1757" at the tail which has a pointed tip. The furniture is brass. The buttplate is secured by square-head nails. The ramrod has a brass tip and is held by a single ferrule. The lack of a ramrod entry pipe was common on British "Sea Service" arms used by the Royal Navy. Provenance: The Norm Flayderman Collection; The Greg Lampe Collection; Property of a Gentleman
