working vintage General Electric wall clock, art deco metal case painted 1950s pink

Vintage GE wall clock, made to plug into a wall socket, working fine! This has glass cover over the clock face, and a 6" x 6" metal housing which was painted pink for a 'makeover' about 70 years ago. Paint is peeling a little, showing bare metal beneath. Clock face is slightly yellowed from age. One knob on the front is missing, which could probably be turned with a pliers if not replaced.
