This is a Ruger Buckey Special . Its a used gun and the finish is quite worn . No rust . The Buckeys were a special run of Blackhawks for a sporting goods chain in Canton Ohio . This chambering was produced in 1990 . And there were 500 made . It is a convertible with 10mm cylinder and 38-40 cylinder. 6and 1/2 inch barrel. I have shot it with 10mm and it shoots and functions as it should. Mostly interested in trades . I am interested in Ruger Blackhawk 4 and 5/8 barrel in 45lc . Or Super Blackhawk 4 and 5/8 barrel with round trigger guard  44 mag . May also be interested in a newer RIA 1911 or similar. Cash price would be $500 and that is firm 
Thanks for looking.
