This is an early Charles Lancaster London England SxS hammer gun with side opener. Chambered for the 2-1/2″ 12 ga. Nice condition gun with a very tight pretty Damascus pattern on the 30″ bbls . They have an medium brown patina. Inside the bore is exceptional. Bright and shiny. The receiver has the typical early European tight scroll work. Delicate and finely done. Overall cond of the wood is good. Hammer springs, trigger springs and action all work well. A very nice old English shotgun.
