Ruger Single Six Convertible, Old Model Three Screw model from 1970. This is the rarest of the Single Sixe convertibles with the 4 5/8" barrel. It is all orignal and has not been converted. Very minor bluing loss and a few light scratches, overall I would say 95%+ condition. Comes with original Magnum Cylinder, no box or docs. Very nice for a 54 year old revolver. Asking $600 OBO
