Hi again

My bike is not a Miyata afterall...it's a Nishiki...stamped right into the frame..previously undetected because of poor repaint and discovered today after it was repainted. I need some help to identify please.
The frame is 50cm, Shimano 600 components (all of them...FB date code so FEB 81, derailleur, crankset, shifters...everything Shimano 600...fancy not plain) Sakae "Road Champion" handlebars, Sugino Saddle and quick release front and rear wheels (6 Cassettes? on the rear wheel). The wheels are Mavic. There is only one spot for waterbottle on the downtube (not one on the seat tube). I don't know the original colour of the bike ? blue because the cables are blue. The rubber on the brake hoods is brown.
Thanks for your time and sorry about the confusion.

nice bike... wonder if we can ID the model.. pics?

i will try, no camera, and it's in the shop getting a makeover...new toe clips, handlebar tapes, waterbottle cage, tires...everything that can change on it.
I just picked up the frame today from the paint guy (really nice metallic blue). The rest of the bike is in a box at the shop. I'm dropping off the frame tomorrow, then I'll have the whole thing brand new-second hand in a week. I need to know the model so my dad can make the decals for me (why I need pics of what it's supposed to look like).
I got the bike as a freebie, so I dont mind spending a little to get it spruced up. According to the shop guy, the components are in great shape, just a little sandy so I'm real happy with that. I plan to use it for a Try a Tri this May. We'll see how it goes...if I like Triathlons, I'll upgrade to something new, but I think I'll be happy with this bike for a while since it turned out better than I expected.

I put a bunch of miles on a Nishiki Royale I bought in 1981. It's pretty much the only bike I regret selling.
