Lest we should forget the long silent, Chuck Schmidt's Campagnolo Timeline ... it can answer many of our basic dating questions. For the caliper changes, scroll on down to 1983:

Brake Calipers NR 2040: 1978 - Mid-1980's SR 4061: Mid-1980's - Late-1980's
I am trying to identify whether cursive or block type face for 1984 Campag brakes and encountered another puzzle (for me). Looking at the photos, the only difference I see is the type face: block for NR and cursive for SR. Is this the only difference on the calipers? I cannot discern if brake blocks are different: NR, steel; SR, alloy.? (Yes, levers, I'm supposing are different: NR smooth while SR drilled).
Thanks
