According to Sutherland's 6th Edition, the "S - U" Record hubs use nine 7/32" balls in each front race, and C-Record uses ten 3/16" balls in each front race. Triomphe and Victory hubs were cosmetic variations on Gran Sport ("Tipo") hubs and used nine 1/4" balls in each rear race and ten 3/16" balls in each front race.
AFAIK, all Campagnolo rear hubs used nine 1/4" balls in each race, including the "S - U" and C-Record versions.
