[R-390] I was unaware they made this cover(pics)!

[Glenn Little WB4UIV]

These could be "black out" covers. The R-390A does not have a dial light 
dimmer. When the radio is used in a shelter, at night, there would be a 
requirement for a black-out door or turning off/covering up all light 
producers for someone to enter or leave the shelter.

Just a guess.
