I found this vintage shogun on craigslist but can't find any information about it. It's not on bikepedia and I couldn't find any old shogun catalogs. Does anybody know what year this is and what components would have come on it? The only thing I can tell is it is a chromoly double butted frame. I also tried to get an idea of the age based on the head badge but had no luck.
