EE89 Time Interval Apparatus

This device rang the bells at all the observation stations and plotting room to govern at what times the target headings were recorded verbally over the telephone. They are similar in function to the device used in the late 20th century to ring bells in a school. The example in our museum was found in the war reserve bunker at Ft. Abercrombie by the park staff.
