Cannon style muzzle on the detachable barrel, with the chamber bearing an "R/B" stamp, London Crown "V" and "GP" proofs, and "COLLUMBELL LONDON" on the top. Border engraved lock plate, with "COLLUMBELL" engraved below the flash pan, and a sunburst pattern on the trigger guard. Smooth stock, with an ornate silver reverse plate, thumb shield and grotesque face buttcap.

Very good, with a polished appearance to the steel, mild discoloration on the barrel, and a small amount of pitting concentrated around the vent hole. A fine aged patina is showing on the silver, with a small dents on the reverse plate. Stock is good, with cracks and a few dents. Mechanically very good.

As "A", but with the barrel and chamber marked "1" on the upper right side.

Very good. As A, with fewer cracks. Mechanically fine.
