Here's a weird one I just recollected for another thread the other day which is actually more interesting in the context of this thread. It appears to be a post war improved S frame in factory nickel I would have liked to have grabbed this one.
The serial number seems way late for an long action
That's truly a puzzle of a gun! If I owned it I'd letter it to find out how it left the factory. If it's for real it would be near one of a kind status. I believe that it's a Frankengun though.
Possibly, but I just looked up the 1917s and there was a series of post war transitional 1917s and the serial series did overlap with that serial number. Only the nickel bit contradicts SWSC. The grips are correct for that period too. I am guessing it's at least a legit post war transitional 1917, with a good looking nickel finish.
