I just picked up a Nishiki yesterday. Wasn't really planning on it it just kind popped up. The colors is what got me actually. I just had to have it. But it seems to be a bit of a mystery as to what it actually is. I can't find what model it would align with.

The serial number is EA100806. So from my understanding it is a European frame, made in 1981 for likely 1982. I am in Canada so it could be a frame that just ended up here. It has full Shimano 600 components, and Ambrosio Elite red annodized wheels. The only parts that have been swapped out are the tires, chain and cables.

The paint seems to be original. Where it is flaking off it chips off to bare metal. It is cracked and crazed like a laquor based paint would, and there is no clear coat. Besides being extremely dirty and rough paint it is in decent shape. I plan on stripping it all down and repainting it anyway. I would just have to find the propper decals for it or have them made. Some seem to be missing like the Tange steel decal and the Handcrafted by Kuwamara decal on the chain stay.

I have looked up what I could for catalogues but the color and components specs do no line up with anything I can find. Everything from the early 80s seem to have Sun Tour or Campy for the higherend models. And I know with 600 everything this wasn't an entry level bike.

Does anyone have an idea what model it could be?
