Subject: [CR]D-shaped Campy caliper arms... when introduced?

I have a set of later script style campagnolo calipers. These have somewhat of a "D"-shaped cross section in the arms as opposed to the earlier "C" shaped cross section.

When did these D-shaped arms first appear?

In Ray Dobbins' excellent group of 1984 Bianchi Specialissima pictures http://www.raydobbins.com/ebay/bike-bianchi/bike-bianchi.htm

He shows brake calipers that were "reshaped" then pantographed. They weren't reshaped from C-section arms were they? Ray?

So, 2 questions: 1) when did the script style (D-section) calipers first appear, and 2) what cross section did Ray's special caliper arms have?
