Only an estimated 400 of these C.R. Alsop Navy revolvers were manufactured in 1862 and 1863 without the earlier sliding safety mechanism. They were manufactured with fluted or unfluted cylinders. This example has a brass blade front sight, frame groove rear sight, "C.R. ALSOP MIDDLETOWN CONN./PATENTED JULY 17th AUGUST 7th. 1860 MAY 14th. 1861" on top of the barrel, "C. R. ALSOP PATENTED/NOV. 26th. 1861" in one of the cylinder flutes, matching serial numbers, and a pair of smooth, nicely figured grips. Charles Alsop and other members of the Alsop family previously worked on the similarly designed early Savage revolvers.
