Total production of Model 1860 Army Richards conversion revolvers is estimated at approximately 9,000, and most of those are the standard model rather than this transitional 2nd Model/Type II variation which has the Richards-Mason breech plate and hammer but retains the barrel lug type and ejector of the original Richards conversion. It has blade and hammer notch sights, the one-line New York barrel address, the two-line 1871 and 1872 patents on the left side of the frame which was originally a percussion frame cut for use with a shoulder stock, "44 CAL" on the left trigger guard shoulder, matching visible serial numbers (including "3791" on the loading gate rather than an assembly number), and smooth walnut grip.

Very good with primarily mottled gray and brown patina, strong traces of original finishes in protected areas, some mild oxidation/pitting, numerous dings along the left side of the barrel and side of the cylinder, aged patina on the brass, and mild overall wear. The markings, including most of the cylinder scene, remain distinct. The refinished grip is also very good with smooth oiled finish, minor handling and storage marks, and a few slight flakes at the edges. Mechanically functions, but lacks full cock and trigger flies forward when cocked. This is an important transitional variation missing from many collections.
