Subject: [CR]Freewheel threads on hubs...when did they start telling us what the threading was?

I just rebuilt and polished up a lovely set of high flange Tipo hubs. They had a Cyclo '64 five speed freewheel on them, so I am assuming them to be a French thread, but I see no such designation on them. Is there an easy to tell the threading on hubs when it is not specified on them? When did Campagnolo start telling on the hubs what the thread scheme was?
