I've got a Nishiki Sport here with a serial number that reads 677962, Made in Taiwan.
The bike is burgundy in color with gold leaf, oriental looking lettering. Its got the old metal crown headbadge.
It came new with Suntour Honor derailleurs, steel cottered cranks, steel Araya rims with 27x1-1/4" tires.
The brakes were Dia Compe center pull with matching dual levers on a steel handle bar and Jun stem. the frame has no braze ons at all, all cables have chrome Suntour cable stop clamps. The seat post is knurled chrome steel.
I've owned the bike since at least the latter part of the 80's and I thought it was an older bike back then.


Also, I've got an International Ser. KS324156
This came with Araya narrow alloy rims, LF shimano hubs, Suntour VX RD, alloy Champion bars, SR stem, Dia Compe center pull brakes and dual levers, Cycle Pro 27x1-1/4" tires, alloy rat trap style pedals with toe clips, and a hard leather saddle marked Made in Japan on an SR aluminum seat post.


and a Sport, Ser. 1125310 on the left drop out and G0581 on the right drop out.
This Sport came with Femco steel wheels, Sanshin LF hubs, Suntour Honor RD, Steel bars, SR stem, and Silstar cranks, and Dia Compe center pull brakes with dual levers, Cycle Pro 27x1-1/4" tires and counter balance type pedals. The saddle was a padded, quilted pattern vinyl model with two chrome springs. It had a chrome steel seat post.
