IMO,
A stock is ruined once a Repro/Faked Stamp is applied.
We know many were lightly stamped and easily wore off with general wear and tear.
Others sanded off when rack numbers were applied.
Repro parts can be replaced......but that nice piece of old growth walnut is ruined for life.
Are we also at the stage where Replica Stamps are acceptable?
I hope not,
