Pics of mine here. Nicest track frame I've ever ridden. Made by a Mr Ogino in Kyoto, Deathhare is correct in that he no longer makes frames except to do repair work for professional riders still racing his frames, and rather does steel sculpture instead. He also did all the graphic design work for the frames. Not a lot of these frames around, they make 3Renshos look common.

Edit: A pic of mine (not the original fork).
