Colt Navy 1851 and Remington New Model 1858
I am not an expert on such guns but I picked up these two recently and wanted to get opinions on importance and potential value. The Remington appearance is good... no rust and only minor nicks on grips. Can't find a serial number but gun is marked as patented Sept 14, 1858. Has "C. A. 1872" engraved forward of cylinder. Trigger mechanism works but cylinder does not spin properly. The other is a Colt Navy 1851 with serial number 116114 - assume made in late 1860s to early 1870s. Trigger mechanism does not work. Some light pitting from rust. Welcome any feedback on these guns.
