I think that RG (Rohm Gmbh of Sontheim/Brenz Germany) went out of business in 1986. Due to the GCA 68, they could not legally import into the US, so they built a factory in South Florida to manufacture their product. RG was the original "Saturday Night Special". There are many horror stories regarding the RG brand, and to some degree, most are probably true. I woudn't expect any RG to be worth anything other than fodder for a gun buy back program.
