those are Jay Scott grips and will fit ANY of the early A-54 frames, MK I OR the RST's...nice grips,look really neat when the old medallions are put in them.......
Good luck
Rugerguy is correct. If you read on the grips it says:
.22 Standard Model
.22 Mark I Target Model
Also both the Standard and the Mark I target model has to have the A-54 frame as Rugerguy said. That frame was changed in 1971 I think, so those grips will work for guns from 1949 to sometime in 1971.
Thanks for the info guys. I bought these as a gift for a friend I sold an early 80's RST 6 to. They didn't fit so he gave them back. I only have MKII"s now so these are surplus. Joe
