Now as to the components:
Hubs: Sun Shine Pro-Am hubs front and read stamped "76" and they spin like butter still.
Sugino Crank Arm (130 BCD never sure if get that right BCD/BDC you know what I mean): stamped 47-11 which I believe is November 1972
Rear Dearailleur: Shimano First Generation Dura Ace Black marked "X A - 2" , guess February, 1976 (Could not find marking on First Generation Dura Ace Black front derailleur.
Will go take some more pictures and post in a bit, this is as close to a time capsule as my Nishiki Professional, except instead of Campagnolo gruppo, other than the Sugino cranks and Sun Shine Pro-Am hubs the rest is Shimano Dura Ace First Generation Black.
Again any light you can shed on this bike from the above is welcome.
