Just picked up this Nishiki mixte- code on frame says G0584 (Giant-manufactured in May, 1984). Sticker on tube near bottom bracket says "Taiwan." Brakes are Dia-Compe sidepulls, rear derailleur says "SY-Japan." I can pull serial numbers off them later when I have more time to go over her. 50" frame, rides very nicely. The seller put new Kendas on it. The brake levers say "Schwinn." Overall I'm extremely happy with her and she fits me perfectly (5'5" female)! I've only had her for 2 days and have been too busy to ride more than a few blocks and it's KILLING ME.
