You're better off ordering a Mauser or Mauser style gun from a place like AIM, J&G, SOG and Simpson's than Mitchell's, just because you pay less for a more original piece.
And the saddest part is that Mitchell's is doing it to Luger pistols now. Oh, and since they are a regular advertiser in both The American Rifleman and Shotgun News, you'll never see a bad word about them in those publications.
