41 caliber. Elaborately engraved with a leaf pattern on the entire gold finish frame and backstrap. Barrels are a high polish blue with just some wear at the muzzle edge. Trigger and hammer retain most of their blue. Mother of Pearl grips are in very good condition. Nice action and bright shiny bores. Gun is fitted in a nice walnut case that may have been relined. Cartridge block included holds 11 cartridges. Original key is present. A very nice little Remington!
