I replaced mine of course, and I wrote the CMP fellows a nice note asking for another WWII vintage if they could manage it (the first was 1942 era and almost 100% Springfield). Well, those boyz sent me a mint 1943-vintage that was all original except for the barrel. Unlike the first one, this second purchase was BLACK with cosmoline -- took me two weeks and a gallon and a half of mineral spirits to get it clean.
Life is good!
