Didn't Kimber make a bunch of sporters out of some model 1938 Mausers. I'm sure I saw one on a rack a few years ago. I had an M38 carbine in it's original configuration at one time. I remember taking it to a gunsmith to tap the receiver for a scope. He said he wouldn't work on it because the metal was too hard or some such nonsense. That discouraged me and I sold it. Later found out it was BS.
