The 1851 Colt revolver, also known as the Colt Navy Revolver, did have serial numbers, although the practice of serial numbering was not as systematic as it is today. Colt began marking their firearms with serial numbers around 1850, and many 1851 models feature them, but not all. The absence of a serial number does not necessarily indicate a counterfeit or replica, as early production methods varied. Collectors often use the presence and format of serial numbers to help date and authenticate these revolvers.
