A rare film used Colt, not often seen in films. The IMFDB lists the Holmes films and Will Penny as the only use of the shorter barrel shopkeeper model. It can also be seen in THE SPIDER WOMAN and in PR shots for other Holmes films at Universal in the 1940s. It is primarily Dr. Watson's sidearm, but often borrowed by Holmes. It, of course, bears the stamped S on the frame. It can be matched to the loss of finish on the cylinder and barrel, as well as by the corrosion. The cylinder pin has been replaced with a chrome button. This model Colt is also noted for the bird's head shaped grip and long, flat, thumb area above the grip and enlarged trigger guard.
