Am unfamiliar with the apparant model name seen on the transfer affixed to the top tube.
The workmanship, paint finish, chrome and Campagnolo 1010 frame ends all point to a quality model.
Would be of interest to know how the small transfer on the seat tube reads.
Headset looks to be original. Nearly all of the other fittings newer than frame but from a wide range of years. Brake calipers are the latest item.
Additional plus: no sign of abuse or rough treatment. Frame in most excellent condition for its age.
