your rg model 14 was manufactured in the 1960's.
RG model RG31 Caliber 32 long manufactured by RG industries, Miami Florida
German
15-50 USD.
Ruger has never made a model with that number. You might be referring to a RG, which was made in Germany. No sn records.
$25-$45. Low dollar firearm of indifferent quality, no longer manufactured.
I do not believe the RG 14 is a Ruger. These were inexpensive German made handguns (Rheinmetal Gemeinschaft) that sell for $25-$50. IF your firearm is marked RUGER on the barrel or frame, I could be wrong. If it is marked RG, not a Ruger.

To determine the age of an RG Model 14 using the serial number, you would typically need to refer to the manufacturer's records or a reliable database that correlates serial numbers with production dates. RG revolvers were produced in various years, so the specific serial number would provide a more precise age. If you have the serial number, you can check online resources or contact the manufacturer for detailed information.
