To determine the age of an RG Industries revolver model RG23 with serial number T452477, you would typically need to consult the manufacturer's records or resources specific to RG Industries, as they can provide information on production dates based on serial numbers. RG Industries was known to produce firearms primarily in the 1970s and 1980s, so the revolver is likely from that time period. If you have access to a firearms database or a collector's guide, you may find more precise information regarding its specific age.
In the context of the RG 38 Special, "RG" stands for "Reichsgewehr," which is a German designation referring to the manufacturer of the firearm. RG firearms were produced in Germany and are known for being relatively inexpensive and commonly used as starter or training guns. The "38 Special" indicates that the revolver is chambered for the .38 Special cartridge, a popular caliber known for its versatility and manageable recoil.
Could be Sauer, Schmidt, Rohm, RG, Gecado, or any of a dozen others.
I also own one (different model #), and my best estimate is that it was produced in the mid- to late-1970's.
Frame
The RG Model 22 is a .22 caliber revolver produced by RG Industries, which was active primarily in the 1970s and 1980s. The specific age of a Model 10 would depend on its serial number and production year, but generally, you can estimate that these models were manufactured around that time period. For more precise dating, you would need to reference the serial number against manufacturer records or firearm databases.
