What I thought was a legit rebuild now has me guessing? I have a 1941 S.A. garand I thought was simply re-barreled in 1946. Every part on the gun is S.A. but the only thing left from 1941 is the reciever. However all the parts are possibly 1946 & older. Would a re-build tear it down to the reciever & replace every single part? The stock also is a S.A. rework with denmark markings. Any input to make me feel good about this would be appreciated.
