Four things say that this is a high-quality frameset :

(a) The reinforcing tangs on the rear brake bridge, found on high
quality frames.

(b) The barrel for brake mounting on the rear bridge, found on high
quality frames.

(c) The cinelli fork crown.

(d) Chainstay brazing treatment.

However, the lack of bottom-bracket cutouts mean this is _not_ an
absolutely top-flite frame. The very very best frames from the 1970's
and 1980's had a cutout on the bottom of the bottom bracket to lighten
up the frameset.

I'll be the frame and fork together weigh 6.5 - 7.0 pounds. The very
best frames of this era would weight about 6.0 pounds.
