RG model RG31 Caliber 32 long manufactured by RG industries, Miami Florida
The majority of RG revolvers were very low value firearms when new. An RG 10 may be worth $20-50, depending on condition.
Could be Sauer, Schmidt, Rohm, RG, Gecado, or any of a dozen others.
Anywhere from $20 to $2000. Depends on the revolver, its make, model, and condition. An RG brand revolver might be worth $20, a high end Colt or S&W target revolver from the custom shop will be worth a lot more. If you can post here again with some information on your revolver, we can try to give you a better answer. PS- in the 1896 Sears catalog, their cheapest firearm was their 69 cent .22 Short revolver.
Not really worth the time or money. If you have to have it done, let a gunsmith do it.
