Need some research help folks

Bill,

I have a friend that has a beautiful all matching (apparently) Mauser Banner that I would challenge anyone to identify the sideplate as being mismatched except for the serial number used as a sequence number inside the sideplate. I have just always made it a habit of checking this number, and when I found that his was a mismatch (not even close) even though the number on the outside matched I didn't have the heart to tell him the pistol was mismatched.
