ROHM
Depending on condition, between $50 and $75. These are alloy framed revolvers of indifferent quality.
I do not believe you have a Ruger, but an RG- Rohm Gemeinschaft. Two very different companies. The RG is generally a low value, low quality firearm that was made in Germany. Value is based on condition, but may be $25-$75.
25 USD
The ruger model RG23 CAL 22 LR is between $25 and $45. <><><> Above is correct. RG does not stand for Ruger. It is a German abbreviation for Rohm Inc. These were German handguns of very low value and indifferent quality. Please have examined by a gunsmith before attempting to fire.
No production records available. Import of most RG handguns to the US stopped with the 1968 Gun Control Act.
30 or so
rohm is an old German import. no value and not too safe to shoot.......
Most Rohm revolvers were considered low quality/ low value firearms. Depending on condition, $100.
20-50 or so
I believe what you have isn't a Ruger product, but rather, a Rohm Gmbh revolver, manufactured in Germany, and imported into the country by R.G. Industries. The RG-23 used the .22 Long Rifle cartridge.
