Regarding front mech -
The original Campag Record model launched 1959-60. It came with a housing stop on the body up through the late 1960's. One small variation is whether or not the housing stop is slotted for the gear cable. The earliest ones were non-slotted and then the slot was added.
There are plenty of other front mechs designed to work with housing so you do not need to necessarily look for an early Campag Record. A new old stock example came up on ebay recently priced by seller at $499 so they can get dear... There are plenty of Huret and Simplex models, for example, designed for use with housing.
