Here is a picture of the 1952 World 3-C tournament which was held in San Francisco and run by the BCA.
Unknown - Welker Cochran - Referee, Sebastian - Tour Secretary, Charles McElligott - BCA Official, John Canelli
Irving Crane - Masako Katsura - Willie Hoppe - Kinrey Matsuyama - Joe Procita
Ray Kilgore - Herb Hardt - Jay Bozeman - Arthur Rubin - Joe Chamaco - Tex Zimmerman
I saw three of the players play (Crane, Katsura, and Procita) and had a cue made by Zimmerman. A friend(?) of mine once tried to steer me into a one pocket game with Procita. I declined as I wanted to play nine ball.
