I agree with Gary. Those grips are from a 3rd. model single shot. The radius on the backstrap cut on your grips is a smooth radius from top to bottom. The backstrap cut on 22/32 HFT grips has a step 5/16" from the top, where the radius begins. As to the value, nice grips can bring up to $300. Your's, in present condition, maybe $100.

Richard,
You're confusing the extended Regulation Police grips with one screw and the above extended target grips with two screws.
The target grips fit over the rebated grip frames without needing a different recess cutout on the backs. Target grips are made to fit both rd butt grip frames and the rebated RP grip frames. They were used on or could be special ordered on:
3rd model SS
22/32 Heavy Frame Targets (Bekearts)
22/32 Kit Guns
32 hand ejector and RP target models
38 S&W HE and RP models
Rebated .32 and .38 S&W RP grip frame and grips:
