My Nishiki International, purchased off CL a couple of months ago. It was advertised as a 1978, but according to the serial number (KG 52378) it's a 1977.

The previous owner upgraded/changed a number of components, so I don't know what is original. The current configuration is:

Derailleurs: SunTour Cyclone, the front has a TD date stamp, the rear has a TH.
Shifters: SunTour Power Shift
Brakes: Dia-Compe
Rims: Araya (F), Super Champion Competition Gentleman (R)
Hubs: Shimano (F), Normandy (R)
Crank: Sugino Super Maxi
Pedals: Kyokuto Top-Run
