My immediate impression was a Super LeMans. However, they typically came with double butted hi-tensile steel during this era. Still, that post size is between what I would expect for double butted hi-tensile and CrMo from Tange. Components most likely to be OEM is heaset and crankset. The latter is typical of Super LeMans from the era.

Not a Pro-Tour as they had direct mount centre-pull during this era. I can't recall seeing a Super Elite without bottle and shift lever braze-ons or chrome extending onto the stays and blades
