There were four people who manned the watchbox. The two shown are Carlo Rodia and Tom Garland. The two not pictured were Norman Bennin and Norman Flint. Norman Flint used to work on a Monday only which gave him the nickname “Monday Norman,” he is now 93.
In the second photo, keys can be seen on the desk. Note the length of tubing attached to the keys. This ensured that nobody put them in their pockets before going home!
