This was an earlier (maybe first generation) Nishiki Professional. IIRC, it's about 1973 or so. The same years as the orange Internationals that occasionally show up on eBay. The ONP Pro was later 70's and were much more "Italian" in style and ride...
By the way, the item number is 290144836899 for anyone looking.
