I bought some time ago a 1957-proofed FN in .357 H&H - which I think to be a Deluxe model, from Joel Dorleac, see http://www.dorleac-dorleac.com/arme/mauser-pirschbuchse-30-06-2/?lang=en . As I wanted some work to be conducted on the rifle (rifle scope fitting, extending the LOP, some wood work, etc.) we ended-up with an almost complete restoration and with a rifle much different than the one we had started with, see http://forums.nitroexpress.com/showflat.php?Cat=0&Number=277232&an=0&page=1#Post277232 . That's still a FN for the action and barrel, but for the style it is now much closer from British or Dorleac classic rifles.
