“Navy”, that would likely be a replica of an 1851 Colt Navy Model. The 1836 Patterson was Colt’s first revolver.
If the law did not allow me to keep modern cartridge guns, I would definitely keep a few percussion revolvers and maybe even a few single shots.
The biggest weakness other than the slow loading is the percussion caps sometimes come off the nipples.
“a replica of an 1851 Colt Navy Model”
Correct.
