The suction cups are usually petrified and or rotted by now. Rubber typically never ages well 5+ decades into its life.

These will work on the AM band with a cheap 1R5 (the 1R5 won't oscillate into the SW bands). These should be serviced to prevent possible filament overvoltage on the 1L6...Those are rare expensive tubes; wasting them by gambling on the chassis state is not a wise move in my book.
