I read somewhere that a late IHC M1 Garand would have mostly Springfield parts or possibly mixed. Somewhere in the 5.01-5.18 million range? I have one that is in that range with all post war Springfield parts and a 2-55 SA dated barrel. Is this correct? The guy who wrote a book about the IHC was the one that said this but I can't remember where I found the info from. It's not popping up under google anymore.
