My 6-page brochure for Nishiki (picked up in 1976, IIRC) shows no "Pro" or "Semi Pro." Top-of-the-line in it is the "Competition," which is pictured with Sugino crank w/chainguard, barcons, suicide levers, randonneur bar, chrome spoke protector, ,kickstand, brake cable secured by 3 clips. Text sez Tange chro-mo DB tubing w/wraparound seat stays. I didn't note down a price, unfortunately. It doesn't look like Nishiki was aiming close to the high end at that time.
