I have seen only one carbine which was completely WWII-original, and it was a Saginaw. A friend bought it at an estate sale for $200 about 10 years ago, had no idea what a treasure he got. Almost all Carbines were rebuilt and upgraded after WWII and matching parts sources was not a priority. My carbine is a combination of components from everywhere. I bought it a long time ago from an ex-GI who brought it home with him sometime after the Korean War. But it was pure GI and hadn't been Bubba'd.
