The Rohm/ RG revolvers were generally very low cost firearms of very low quality. Values are generally in the $20-$40 range.
Rohm and RG revolvers were made in the early 1960s, and banned from import to the US in 1968. They are of very low quality and worth, and there is no known database of serial number info.
While the value of any firearm depends on its condition, the RG revolvers were very inexpensive firearms when new, and are typically worth $50-75 US.
It will probably cost you more to find one and have it installed than the piece is worth. They were made on the low side of quality to begin with.
"Rohm Gmbh" which essentially is Rohm Ltd. in German.
