Another version of Blondie would be cool, especially for those who haven't got one yet, but the only things needed to make the first version of Clint into a SA GBU Blondie, I think, would be the addition of the Colt 1851 Navy cartridge conversion pistol he used in the film (see Entropy Chicken's pic of it below). The Sharps rifle would be a nice addition, too.
* E.C. - Thanks for the time conversion link, btw. Much obliged.
Yup, Blondie's GBU Colt 1851 Navy with snake grips would be great. And a bounty hunter Blondie would need to come with the modified Winchester/Henry rifle he uses to shoot Tuco's rope. The Sharps rifle would be a great separate piece to add to the previous Gunman figures like the Buntline with stock. No one makes better weapons than Rainman! They are perfect and I'd like to see him make those rifles.
