We can help. We are the main Factory-appointed UK Service Centre for Campag and have taken over from Mercian in that role (well, actually, there was another SC between) ..
Mercian are also a superb choice and we can absolutely vouch for their excellence.
There are some issues around 9s levers, it depends on version, age and is not *quite* straightforward in every case.
Veloce internals can be swapped into Record or Chorus bodies in many cases but it’s not a straight swap, there are some subtle differences that you need to be careful about that make the difference between it working – and not.
PM me or contact us via our website if you’d like?
Cheers
