Factory cases for S&Ws of that era are few and far between. It is much more common as Ed says to see the cases made up by the big distributers. Even those aren't common though. I can't read the inscription on the lid. The few factory cases I have seen didn't have a name inscribed on them and they invariably had a paper label glued onto the inside of the lid showing directions for operation. Having said that, if it were my gun and case I would letter it because with Smith & Wesson one can never say never. To me it looks like some of the cases I have seen with guns that shipped to Europe. Are there any European proof marks on the gun.
