FRUIT MACHINES IN QUEEN MARY
Sealed by U.S. Customs
NEW YORK, Wednesday
Twenty "one-armed bandit" fruit machines in the liner Queen Mary were locked under Customs seal when she arrived yesterday. New York regulations forbid use of the gambling machines.
Cunard Line officials said the "experiment" of carrying fruit machines in the liner's public rooms had been ordered by their Liverpool office. Crew members said the "bandits" did roaring business on the crossing. - Reuter (sic).
[A Cunard official at Liverpool said: - "This is the second voyage the Queen Mary has made since the 20 machines were installed. They have been popular among passengers but we cannot comment on questions of revenue or the American regulations."]
