Back in the day (for me, mid-1970) you got a SR or NR bottom bracket, 68mm or 70mm with cups depending... no mystery about BB axle sizes. And the two bolt seat post? Never used the special wrench at all. Box end wrench, adjust the angle of the saddle and never have to touch the thing again! Freewheel cog combos? Regina six speed 12-21 or 12-17. Things were simple when your goal was to go fast.

BTW, Campagnolo issued a chart with all their BB cup and axle dimensions.
