Could that be a RG, a Rohm Gimb, German made 22, or 38?
The logo on the grips appears to be "MF". This probably corresponds to what will come out of your mouth the first time you shoot it.
Looks like an RG 23 I bought new in 1970-first handgun. Threw lead badly out the side due to sloppy cylinder fit. Truly a “high quality” piece. I think I gave $10 for it and that was $9 too many![]()
