I really appreciate this thread and thought I'd post a few photos of my old Nishiki (serial # KS175349). I purchased it in the fall of 1972 and used it as a commuter bike around the U of W campus. Not ridden much since then. Suntour derailleurs -- Compe V on the front and GT (#4532) on the rear. Sugino crank set. Diacompe brakes. Only thing ever replaced was the tires and brake pads. I'll see if I can post a couple of pictures of it. Didn't figure out how to post a picture. Will try later, maybe. Duh! Got it.
