Glad to help: The serial number is located on the bottom of the aluminum metal frame of the grip, that is, the very bottom under the grip. Point of interest, the RG-23 six shot .22 caliber revolver, was made in two barrel lengths, 1.75 inch and 3.38 inches. It is a cheap, yet fairly well made revolver, and the parts, and usually the whole gun is/are made by Rohm Gmbh in Sontheim/Brenz, Germany. It can be worth between 50 to 75 US dollars depending upon condition.
20-100 or so
30 or so
20-50 or so
It was believed that Rohm was plotting a coup against Hitler. Himmler told Hitler this so he could get rid of Rohm so he could rise through the ranks of the Nazi hierarchy. His execution had nothing to do with his sexuality.
Rohm, or RG, was a maker of low dollar handguns of indifferent quality. From the mid 50's to about 1968, their products were imported from West Germany to the US. Import was blocked at that time by the 1968 Gun Control Act for most of their products- they could not meet the tests for size, metal composition, etc. Company no longer is business, no public SN database, so that is as close as I can get. Value anywhere from $10-$50 for MOST of their revolvers, depending on condition. You did not give us a model or caliber.
10-80 USD or so
50-150 or so
40 or so
50-160 or so
$25 or so. Low value handgun.
50 USD or so
