AFAIK, all Campagnolo rear hubs used nine 1/4" balls in each race, including the "S - U" and C-Record versions.
Velobase has
Triomphe with: "Front Bearing Size/Count 3/16" 9x9"
Victory with: "Front Bearing Size/Count 3/16" 10 x 10"
C-Record with "Front Bearing Size/Count 3/16" 9x9"
The ball sizes match.
