I haven't found much myself. Hoping that someone else might know more, but it sounds like a fruitless search. Too bad

I'm in the process of getting it fixed up right now, but when I am done I will post some pics. Tubing? Well, I saw a decal that said CrMo triple-butted, and the fork said Ishiwata. I'm pretty sure the fork is original (trademark kangaroos), so...could I say Ishiwata, triple-butted? (My bike knowledge began with working on this one, so I am still building my vocabulary)
