I just came into possession of a IBM carbine tell me about it

Therein lies the definitions of original As manufactured, Rebuilt as issued, and all correct parts restoration. And then there is the BUBBAized which may or may not have all GI parts. I fully understand what you are saying. Unfortunately, it is often nearly impossible to tell some of these categories apart. A well done restoration can be easily mistaken for an all original as built. Those of us who have been collectors for years can USUALLY tell the difference, but I've been fooled more than once.
