The Walch Revolver is a .36 caliber cap and ball black powder revolving action handgun, designed by Walch Firearms & Co. The revolver was patented in 1859 by John Walch.
The revolver has two variants; a five-chamber model and a six-chamber model. Each variant is capable of firing two shots per chamber, when completely loaded. There are two hammers, and depending on the model, one or two triggers.
Roughly 200 Walch Revolvers were produced between 1859 and 1862, making them quite rare.
