I looked at a couple J.P. Sauer k98k's today that belong to a friend and have a question. They are both mismatched, one is a ce42, the other a ce43, and both have the left side of the receivers milled flat where the mod. 98 would be, but I could not see any holes in the receivers and the left rail looked thicker than normal. Could these be lsr or ssr sniper receivers that weren't finished, and would they be worth much as being mismatched? I appreciate any info given.
