So far, so good. The frame has some minor scratches and wear, but I should be able to clean it up well enough. The yellow stickers say "Jingane" and "Cr.Mo Butted Tubes." I'll put it together with black-and-silver parts. The Gran Compe levers are black anodized, I also have some Gran Compe black cantilevers, a Nitto Technomic stem in black, and some black edition, large flange Dura Ace 36h hubs. Derailleurs are the Suntour Le Tech I mentioned earlier. Otherwise I'll put on a set of black and silver Cyclone derailleurs to match the other parts. It should take me about a month to get it all together. I hope.
From what I can find out about maker, they began making bicycles in 1906. They were established in Chofu, which is a suburb in western Tokyo, and 4 generations of makers have been producing bikes there. The other examples of these bikes I have been able to track down are usually lug-framed, always made of Reynolds 531 steel. The company produced custom made bikes for a number of customers, the most famous of which is Haruka Takachiho, one of Japan's top science fiction writers. He also wrote a couple of novels about cycling, as well as a cycling manga series.
