Manufactured from 1870 to 1912. The top of the barrel is marked "-COLT-" in italics and the left frame side is stamped "41 CAL". The grips are numbered to the gun. The underside of the barrel has two British proofs.

Excellent. The derringer retains 98% plus original nickel finish with limited light flaking and some scattered light loss along the edges. The grips are also excellent showing limited high edge wear and a few minor handling marks with most of the varnish remaining. Mechanically excellent.
