These are genuine Smith and Wesson wood grips. Open back type that I believe are for the K and L Frame revolvers. Perfect condition, just old and need cleaned. They look like they were new when put in storage, so I am guessing they maybe new take-offs that were removed from new revolvers. I'm going to guess these are 1970's or 1980's production. Specify with the left side cut-out or without. Price is for one set. I kept two sets of these for myself and after a little cleaning, they look incredible.
