This is a cool Civil War weapon! It is an original model 1861 Colt revolver. When you look at the gun it looks very similar to the model 1860 revolver of the .44 caliber size. These model 1861 are slightly smaller all the way around and they fire the .36 caliber bullet. The gun has the matching serial numbers of 21,786 on the parts. Thanks to Mr. Colt's bookkeepers we know that it would have been made in the latter part of 1864. This was the third year of production for this pattern of revolver. The top of the full-length 7.5 inch barrel has only the clear maker's mark that reads "ADDRESS
COL. SAMl
COLT NEW-
YORK
U.S.
AMERICA". These guns were manufactured in Hartford, Connecticut with their sales office being in New York City. It has none of the cylinder scene still visible. The handle of the gun still has a nice looking walnut wood grips intact. The grips have a very pleasing tone all over with a rich look. The action still functions well. This is a nice displaying Colt revolver that is made during the heart of the Civil War.
