I called the guy and I'm going by to look at it tomorrow afternoon. He said he bought it a LONG time ago and it's been sitting in his garage for 20 years. He couldn't even tell me the brand of the bike and it wasn't close where he could check it.

I'm primarily interested in the frameset so are there any oddities I should look out for? Would the rear dropouts likely be 130mm instead of 135mm? The front at least appears to have canti-studs but can't tell about the rear. Is the BB shell likely to be compatible with modern cranksets?

I've been studying the word on the downtube and I'm thinking it might be a Sekai. Some interent images show Sekai's with the name brand in the same spot and the model on the top-tube, very near the headtube, where this bike appears to have some writing. The downtube has one too many letters but I found at least one Sekai that had a symbol after "Sekai". We'll see tomorrow.
