Correct me if I'm wrong, but I don't believe that revolver as pictured in post #10 is what the OP was talking about. My grandfather's (now mine) Registered Magnum was produced in 1936, and has a 5" barrel, hump-back hammer, checkered top-strap, and partridge front sight. When he purchased it new, there was paperwork that was sent to S&W, and some short time later a "certificate" arrived that listed him as the owner, along with a brief description of the weapon. I have the original box, cert, return envelope with cancelled postage, owners manual, etc. Luckily, he bought near a case of ammo, but only fired most of one box, and stored the rest. Someday my kids will own it.
