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 brass 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, frame under the left grip, on both grips, and on the butt. The side plate was not removed but is clearly original.

Fine with 50% plus bright original high polish blue finish remaining and concentrated on the barrel and cylinder, 75% original vivid case colors on the loading lever and hammer, smooth light brown patina where the finish has flaked on the frame, and general minor age and storage related wear. The grips are very fine and have smooth finish, light scratches and pressure marks, and minor edge wear. Mechanically fine.
