1936 airline vintage radio still in working condition

This beauty I’ve had for about 25 years. I would listen to whatever station I would find and I loved the lights and the look of it. I’m sure a collector could restore it. This is a rare piece. Please examine my pictures closely This radio does not have a backing and I don’t really know if they did back then. It’s missing a knob and has scratches but its quite a gem. I’m ready to let go of it. Also the bulbs do get very hot when plugged in. It’s ready for new parts! I’m marking this in good vintage condition . This is 85 years old and still works. . All the knobs do what they are supposed to do The first knob is the on and off the second knob is the volume , then the third knob turns the dial and the fourth knob switches between shortwave , broadcast and middlewave
