As O_D mentioned the whistle, even if it was not completely present and functional if the tank was ever treated and one of the rust encapsulator products was sloshed around inside the tank, that area could well be coated with the stuff and the vent blocked. I know that stuff blocks the pickup tube if tank is allowed to dry in a position where it collects below the tube opening so it could have done the same at the vent if the tank was allowed to dry upside down.
