For what it's worth, on CR in the past few months we discussed when the arrival of Campy recessed brake bolts and short-reach brakes occurred. The '81 Bikecology ad is useful because it shows nutted brakes and long-reach Campy units on that beautiful red Colnago. However, it does have the shorter #1010B dropouts that superseded the long #1010A models on top of the line racing bikes in the mid- to late 1970s. (It also has a *kickstand*, but we'll assume that was just for photographic purposes... )
At any rate, I clearly recall working on 1980 Colnagos with the recessed bolts and short reach brakes, so perhaps there was some variation in production runs for different exporters/importers (possibly sitting on a lot of long reach/nutted brake inventory), or bikes coming from different subcontractors, etc.
