It looks extremely consistent with my 1977 Pro Tour. Many of the letters on my foil "Centurion" decals were gone, and I just removed the remainder. Mine has the same Tange Falcon headset and what appears to be the same brake levers. I was able to salvage my racin' stripes on the seattube.

Only thing that doesn't look right is the seatpost binder bolt. Mine is unmarked, but has a notch on one side and fits inside the ears of the lug.
