I've come across one that was incomplete, but they seem even less common than Riggen. I'm not sure of rarity but $45 seems like a decent deal. I think the one I had was a Cobramite but can't find the pics at the moment (I think I sold the body for about $25). I get them mixed up with Dynabrutes of which a pic is attached. I use the Toy Baron site for my info on the brass cars - Cobramite, Dynabrute and Riggen.
