Campagnolo catalogs up through the mid '80s have a chain line diagram with the QR lever on the drive side.

The only reason this changed in the first years of the GS derailleur ('51 intro) was because it was found that a wheel change could be made faster with the QR positioned on the non drive side as it didn't interfere with the derailleur.

Interesting idea though, trying to group the Campagnolo products around the then new GS derailleur. Here's the product line up in 1951: 1951 Catalog Un-Numbered (both Cognin, France and Vincenza, Italy addresses on cover). Included are the Cambio Corsa, Tipo Paris-Roubaix, Gran Sport front and rear derailleurs, Sport front derailleur (no rear version), bar end shifters (no rubber covers) and downtube shift levers (twin band clamp, hexhead bolt friction adjuster, full length cable housing and braze on version shown), small flange three-piece hubs (alloy flanges pressed onto a steel barrel, QRs with "D" ring), Cambio Corsa/Paris-Roubaix toothed dropouts, Cambio Corsa/ Paris-Roubaix with integral derailleur hanger, Gran Sport dropouts with adjusters, Sport dropouts, "H" tool, dishing tool, freewheel remover, cone wrenches and a fixture that accurately locates the toothed dropouts during frame building.
