Look at the hinges on the canned photo you posted. Notice that the moveable bow, the chunky bit the key screws into, has a square hole on one end. The fixed bow has a strap that goes through the hole, and is bent back along the outside of the bow. That strap and hole make up the hinge.
The tab that lies along the outside of the cuff, is the backstrap.
That is an old method of construction. The newer cuffs of the same type had interlaced bosses forged on the ends of the fixed and moveable bows, connected with a pin. They looked more like a modern hinge. It required more precise fabrication, as the hole was drilled, so the newer style of fabrication didn't realy come in before the advent of more modern machine tools.
If yours has the typical pin rivet, the cuffs are probably worth in the hundred dollar range. If they are backstraps, then they are probably worth more. I believe it was Joe that said he had never seen a backstrap cuff with your markings, which would make them worth even more.
The devil, as always, is in the details. Details are the bane and the glory of collectors. We can agonize over the shape of the ampersand (&) in "Smith & Wesson."
Yours are nice looking cuffs.
