Could you please give the range for the 16 possible combinations for the 4 digit SN on the model 1901?
The pic shown is of a gun with no numbers on the butt, but the same 4 digit number on all of the parts and RAC on the frame, barrel, cylinder, and both grips. Latest patent on the barrel is 3/5/95. Does this look like a REAL 1901? Thanks
This is a rough calculation, and due to the intermixture of civilian and Navy models may vary in actuality.
But the basic calculation is simple. You have the assembly number 7527 as the last four digits. You also have the ‘95 barrel patent date, meaning the earliest candidate can be from the Second Contract of the Army Model 1894, starting at serial 63,000.
So your gun could be a modified/upgraded gun between 67527, 77527 ... to 157527, or an actual Model 1901 with numbers 167527, 177527, 187527, or 197257, after which the slightly different Model 1903 started.
There may be minor technical changes over the years that allow you to narrow this down further. I’m not that much into screws and springs, you’d have to find someone more experienced in those details.
