I wouldn't hazard a guess at the value of that one...Leatherhead or Egghead on here would probably be your best bet for that...But I will say that's a LOT of Smith Collectors' "Unicorn Gun"...Quite a few active & knowledgeable Smith Collectors will go their whole lives without ever seeing one "In The Flesh"...CONGRATS on picking up a GREAT piece of History!... ....mikey357
