Helpful hint of the day:
When testing a whistle button using postwar whistle tenders, make sure they're upright or upside-down. If they're on their side, the whistle relay might connect and blow the whistle constantly. Electronic horns, of course, do not have this problem.
Pardon me while I go put on a dunce cap and join the Amalgamated Association of Morons, Local 6 7/8.
