Everyone who ever won a remtach?

But I don't really think that's what you meant.

Dick Tiger won the 175 crown from Jose Torres in the fight after losing the 160 crown to Griffith.

Toiny Canzoneri won the 135 crown from Al Singer after losing to Billy Petrolle.

Emile Griffith won the 147 crown for the third time from Jose Stable after losing to Manuel Gonzales.

Jack Britton won the 147 crown from Johnny Griffiths after losing to Mike O'Dowd

I think Ike Williams did it at 135 too IIRC.

I'm certain there are dozens of others.
