I was chastised on Shotgunworld, Ithaca Forum, for changing the shape of a pre-war stock. I did reshape the comb a bit.
My reply was, gimme a break, I have $225 in the gun. If it had been a "valuable" gun, I could sympathize with your position.
This guy had been hunting for a vintage pre-war 20 ga. stock, and here was one refinished and altered from original by me. I guess I understood his angst.
