Your grips look like the smooth rosewood grips I used to buy in the seventies. They used to sell Smith and Wesson accessory target grips in a blister pack. The model 67 was the least expensive used revolver in the Smith and Wesson line for several years. I finally broke down and bought what appears to be an unfired dash something with the red insert. It has a very smooth action and at $200, I wondered why it took me so long to take the plunge. Enjoy your wonderful 67, they are a treasure.
