If I remember correctly Jimmy's case was modeled after a C series. And he got out of the business when his two key suppliers went out of business and began to worry about trademark infringement. I don't have pictures with me but the key differences on the case would include slightly elongated lugs, enlarged case tube, slightly higher bezel and overall better finish. The crownguards.... well you know about the crownguards. And I can say with a straight face that my Jimmy's cg's actually function better than some gens.
