Looking for info. for one of my buddies. His m1 carbine receiver says "WIN 1001" Does anybody have any idea what the significance of that marking is? We have both bee wondering for quite some time. Thanks for your insights.
The more pictures the better to help ID it. If you can take a nice clear one of the back of the receiver behind the rear sight. Also if you can take it apart and take photos close up of the trigger housing and such. It sounds like it could be a commercial carbine.
