First, your name is great. I had "Ski Or Die" video game back in the 90's.
The 337's are early 1980's bindings and Salomon didn't start producing skis until 1990 and were cap/monocoque construction. Skis from Japan were Ogesaga (sp?), Swallow and Nishizawa and maybe some that I am not familiar with. With that said, this was probably a promotion ski for Pierre Cardin.
