I acquired a "Made in Taiwan" (by Giant?) Nishiki Sport frame, maybe 1989 from what I hear around the net. Here are the CL ad pics:
The downtube decal read: "Nishiki Performance Equipe" and the top tube said "Sport". the fork and main tubes are 4130 Cro-Mo. Nice lugs, nice cast dropouts. Unicrown fork. There is a number on the seat tube on the left side, just above the bottom bracket. The first character is indistinguishable but after that it says 91009589.
