There were a number of RGs from the mid to late 90's that came with a natural finish. The RG570MHSOL was a limited production mahogany bodied 570 with the same gorgeous oiled finish as a JS6. We also got he RG547 and a couple of years later we had the RG548, both ash bodied RG570 clones in a natural finish.
I beleive they were unfortunately withdrawn due to poor sales
