I come across this a couple of nights ago... typical Motorola set of the 50's, except for one thing... the door (or front cover). Never seen one designed like this.
Somehow I have the feeling it looks to have the dreaded 21EP4... however it does put light on the screen.
The set is nice looking... I wish it were closer. I dig that cabinet.
