Only about 500 of these Navy Model revolvers and 300 of the smaller Pocket Model revolvers were manufactured by Charles R. Alsop of Middletown, Connecticut, in 1862 and 1863. Both designs closely resemble the Savage revolvers also produced in Middletown in the late 1850s and early 1860s. Multiple members of the Alsop family held positions in the Savage Revolving Firearms Company, and Charles was one of the principle gunsmiths with the firm. Thus, Alsop revolvers are clearly refined versions of the somewhat awkwardly shaped Savage system. The barrel has a blade front sight and "C.R. ALSOP MIDDLETOWN, CONN./PATENTED JULY 17th. AUGUST 7th. 1860 MAY 14th. 1861," the cylinder is marked "C.R. ALSOP PATENTED/NOV. 26TH 1861," and the left side plate has "PATENTED JANY. 21ST 1862." The top of the frame has a long groove for a rear sight. The matching serial number is located on the bottom of the barrel, front face of the cylinder, side plate, under the left grip, both grips, and the butt.

Fine with 90% plus bright original blue finish on the barrel, 85% plus original case colors on the lever and hammer, 60% original blue on the cylinder, patches of original blue mixed with gray and brown patina on the frame, spots of light oxidation, and minor marks and scratches. Other than a hairline crack in the left panel, the highly figured varnished walnut grips are very fine and have only minor handling wear. Mechanically excellent. This is a very attractive example of a very scarce American model absent from the vast majority of American revolver collections.
