[QUOTE=iab So to get this straight, are you saying Campagnolo made a Sport hub prior to 1967 that looks very similar to the Tipo hub?[/QUOTE]
The image of the hubs referenced from another thread, with the solid axles are Sport. They share round holes with the Tipos, but the overall diameter is smaller, as stated a "mid flange" or three quarter scale high flange as I see it. Also note the flanges appear more vertical than the Tipos or Record.
1963 is consistant with when these were avail.
A footnote in Campagnolo history, like the Tandem hubs they made.
