"All my 7m Winchesters " Well it sounds like you have a few. Do you have one with an EW flip safety? I saw one sell on GB last year with a fake EW flip safety. Just checking.
Of course the butt plate is not correct. And it is a good try at a restoration. Not a bad deal if someone was wanting one. I have seen worse sell for more. My thoughts are the TH and stock are wrong. The rear sight is wrong. The slide and mag catch could be wrong. The refinish is wrong color and no blued parts.
