Hi, all

I managed to obtain a Miyata for nothing (it was hanging up in a friend's parents' shed, and they wanted it out of there). Apparently they were storing it for someone and they'd lost contact for several years. It's been repainted - the only way I can tell it's a Miyata at all is from the stamp on the shoulders of the fork. My friend's parents could only tell me, "He was a pretty serious rider, and he spent a lot of money on it". Is it possible to identify the model? Here's what I can tell you:

All the trimmings appear to be Suntour, but I can't find part numbers on anything (the bike is pretty grimy). The rims are Amaya. The bike's serial # is L267416 (I think - when it was repainted, it looks like the paint filled in the numbers, so they're a bit hard to read; that last 6 could be an 8). Is this enough information to make an identification?

Also, if anyone knows anything about this bike, do you think it would be worth upgrading to some more modern parts? The bike weighs about 27 lbs., but it rides pretty nice (at least, after the flywheel was cleaned out - it'll be even better with some more work).

Thanks!
