Got the joco back from the frame builder, quick update.
Campy hubs stripped and serviced, re threaded with stainless spokes and trued up on the old mavic rims
Regina Oro freewheel fitted
Campy headset, BB, cranks, rear derailleur and shifters fitted
Weinmann 730s mounted( needed these for their reach)

Waiting on a NOS front mech and an everest oro chain to arrive, can then mount the campy brake levers on my handlebars and plumb it all in.
Not totally sympathetic to original but should ride and look nice.......hopefully
I reckon another month and I'll be riding it :-)
Some pics....
