1) To control expansion with humidity. Icon_smile

2) Philco knew that CA. would require earthquake straps for furnishings in the 21st century, and they wanted to get a jump on the requirement. Icon_mrgreen

3) The radios were getting to heavy, the hole reduces weight. Icon_lol

If I had to take a wag, I would say that hot air was getting trapped at the top of the arch discoloring the finish, the hole provides a vent to let the hot air out. Even thought the back is open the arch support enclosed the top of it and hot air rises.
