Yes Mike...true enough, but that IS part of the rifles history, no matter what you do to it afterwards.
Refinish the stock or not... it's just another chapter in that particular rifles history.
I don't think a refinish destroys it's originality, and yes, too bad the Russkies ground off all the Kraut markings, but after all, they DID loose 20 million citizens fighting them. Can't blame them for being just a LITTLE pissed, and not wanting to grind of the Waffenampts. A shame, though.
Like the old saying goes...imagine if the rifle could talk... and if they did I'd much rather the latest chapter was " Got my stock cleaned up and made real purdy" than "Got confiscated by some ####bagger and fed into the shredder...bye now...been a slice."
Anyways... just my 2 cents!
