Kawamura, Tange #2, just like mine. Except way smaller. And mine is a nice silver/gray fade. And I bought mine in 1987 as a frame/fork only, and built it up with Superbe Pro/Sprint bits. Great bike - I rode the crap out of it, and then my dad rode the crap out of it. Still have it; won't ever sell it.
As a trade-in, I think you'd be lucky to get a benjy out of it. It's just not what "normal" cyclists are into these days.
