Offered here is a rare full 50-count box of U.S. Cartridge Co. .44 centerfire cartridges for the Colt Model Army conversion revolvers manufactured in the 1870s and used a mixture of remaining Model 1860 Army parts and newly manufactured components. These revolvers were manufactured alongside the Single Action Army and are believed to have seen significant use in the Old West. The box features an orange label with an illustration of Colt's metallic cartridge conversion revolver. All 50 rounds are included.

Exceptionally fine, with the opened seal displaying some typical loss along the break, a single split lid edge, and nearly all of the orange label remaining. A box of Colt Model Army conversion revolver cartridges missing from even the most advanced Colt collection.
