Tough for me to say if it is 83 or not.

A shot of the head tube would be helpful - 83 and 84 seemed to have the rounded "wreath" around the "N" and 85 and after had a square N

Plus - International is script on the 83
Minus - inlaid "N" on the seat stays

I redid the International below for my daughter this winter (test ride on saturday), and it had the the Suntour Symmetric shifter braze on mount. And I've seen pictures of presumed 84 Internationals having the Symmetric shifters and Cyclone II drive train, with "International" in block letters . My International also had the Champion 2 tubing label (didn't Tange labels come after Champion?). All this exactly the same as a 1984 Centurion Elite RS I had (other than the Nervex-style lugs). - So I've guessed my International is an 84.

This one was a beach bike that I picked up as a frame and a bucket of parts. Found that Testors Red Metal Flake is an exact match, and got it reasonable looking.

The dating of your Nishiki interests me because I just picked up a Prestige frame (Tange 2 with square logo on the head tube with the inlaid "N" on the seat stays, but in the blue, not the two tone) and have been trying to date it. I'll build up that one for one of my sons over the next year. I'm thinking the inlaid N and Tange 2 dates it closer to 85 or 86, but not 87. Maybe I should head over to the Nishiki Serial Number Database thread....

Love the look of your build. My daughter is thrilled with hers.
