Hello Bill,
www.amicidelloscramble.it Carlo suggested these people and they seem to have lots of reasonably priced new parts.
Also Phill at Road and Race in Australia has parts and is easy to deal with.

I've played a bit with wide case singles, so if I can help your friend let me know.
Regards
Graeme
