Manufactured by A. Uberti in Italy for Cimarron Firearms, this revolver replicates the 1851 Navy Richards-Mason cartridge conversion in an open-top Colt pattern. The frame is roll-marked with "PAT. JULY.25.1871" and "PAT. JULY.2.1872," and the barrel bears Cimarron F.A.
Co. Fredericksburg, Texas and A. Uberti, Italy inscriptions alongside Italian proof/date marks.
The configuration stays true to form: a 7.5 in octagonal, wedge-retained steel barrel; a gated cartridge conversion with loading gate; and the percussion-style under-barrel lever and plunger retained. It is a six-shot, single-action-only revolver chambered in .38 Special with fixed sights—a brass-bead front and an integral rear notch.
Construction and finish are classic: a steel barrel, frame, and cylinder; blued barrel and cylinder; and a color case-hardened frame. The brass grip frame pairs with a one-piece varnished hardwood grip. The cylinder carries the naval battle scene roll engraving associated with the 1851 Navy pattern.
Markings and small details add authenticity and cohesion. The loading gate is numbered with matching "540" to the observed serial, and the gun reflects the period-correct open-top design with wedge retention. The combination of finishes and roll marks delivers a faithful reproduction configured for .38 Special.
