The answer to the trivia question (Msg #108) is #4 which Gil wore
when he first arrived with the Brooklyn Dodgers in 1943.

I also wondered about the Baseball that Gil caught for the final
out of the 1955 World Series. Well!!!My surfing the Net paid off.
Rookie pitcher, Roger Craig, retrieved the ball and wrote the
following on it, "Last ball of Dodgers 1955 season".
