Since we are speaking of the Pista headsets, did SR Pista headsets have a lower stack height than SR Strada headsets, as was the case for NR headsets? And while we are on the subject, why were NR Pista a lower stack than Strada, or for that matter, why did Campy make different headsets for road and track in the first place?

The whole reason this thread started was because of this photo:

I also just received 2 Super Record Pista headsets - one NOS with the thin washer, one used with the thick washer.
Anyone have an idea of what year the switch was made? I don't see any of the PISTA models in the catalogs with the thicker 4mm type.
