Posting for a friend looking for this cylinder. He has the 38/40 but is searching for the 10mm.
A rare revolver that was commissioned by BUCKEYE SPORTS was the RUGER Single Action Revolver in 38-40 and 10mm. This interesting and desirable cowboy type handgun had two cylinders, one for the old 38-40 and a second one for the 10mmAuto. The revolver Buckeye's RUGER Blackhawk revolver (pic) came blued with a 6.5" barrel. I sure would like RUGER to build their new Varquero revolvers in this configuration.
Thanks in advance!
