.... ugh. I don't think I have the patience to track down all the right bits. Especially when I have a couple of 1980s Shimano 600 groups laying in my garage.
Looking at the '87 catalog http://www.stevevance.net/nishiki/im...le_catalog.pdf this frame looks to be the "SPORT" bike.
With all the nicks, dings, and paint damage, it's difficult for me to imagine I would find someone who values the frame in a significant way any time this decade.
On the other hand, I'm pretty much jonesing to powder coat a frame, build it up with 650B wheels, and ride the snot out of it. (rivbike.com says this is a good BB drop for what I want to do: https://www.rivbike.com/kb_results.asp?ID=64) - Maybe tour with it. It seems like it'd be a good candidate for touring. Although similar to the CRESTA Nishiki was selling as a touring bike.

I'm open to other opinions, as the paint stripper probably won't hit the frame for a couple of more weeks. I've got a Raleigh I'm going to use as my first try at powder coating, probably this weekend. - and if the powder on the Raleigh stinks - maybe a whole 'nother plan will come up for the Nishiki and Peugeot.
