Well, OK, I don't need another bike, but I was driving through Butler (Indiana) for work this morning and I saw this bike sitting in front of the 2nd hand shop in town. I immediately saw the long stem tube and slammed on the brakes. The lady who owns the shop told me the price she was asking for the bike so I bought it right there. Actually, I only had $4, but I put that down on the bike and ran back at lunch and paid the rest for it.
Myles has found a similar bike, although this one is in rougher condition and the components maybe aren't as nice.
I don't know much about tubing, but it's 4130 Chromoly.
The head badge is decent.
The model is Pulsar. I did a quick Google search and found lots of Japanese (I think, I don't know which language) entries for the Kuwahara Pulsar, but no pictures. Will continue the search.
Symmetric shifters, as described by Jon in Myles' post above. The rear derailleur cable is sticky and not working very well.
The rear rim is wobbly, but I should be able to true it easily. Will update progress on getting this bike road worthy. I'm looking forward to seeing how it rides.
