Good day, again, T-Mar. On the bike which I mentioned earlier, the front derailleur is Sun Tour Spirt, Maeda Industries, Ltd., 4532. The rear is SUNTOUR GT, also 4532. Before the number on each of these derailleurs is a symbol, which I do not recognize as a kanji: a circle with a jagged line, vaguely vertical. The cranks are Sugino Maxy forged 171 with chain rings using three bolts, rather than five. Pedals are Mikashima #11; freewheel cluster (5), Maeda; pump (with brazed-on pegs), Primus; brakes, center-pull Dia-Compe; rims, steel Ukai 27 1/4; hubs, Sunshine; stem, Nitto forged; handlebars, Nitto Olympiade 115; saddle, Belt by Fujita; seatpost, uncertain. I'll try to learn more about the date of sale, but actually I was hoping that you could verify the date for me. I'm not able to send a photo, since I've never gone digital. Good luck with your project.
