I too was questioning the possible typo, so I asked for more photo's. Unfortunately, too fishy for me.
Rifle s/n matches bolt. Scope mount (renumbered during FTR) matches scope case. Scope case not original to anything but paired up during preservation for storage by "Ball" (which is ok too). Scope s/n stamped into butt.....bubba??
Too many inconsistencies for my dollar.
