I've done some research and I believe that the left chassis is a modified 37-650 or 37-660. The power supply chassis on the right appears to have two separate rectifier/audio output systems on the one chassis. The tube lineup on the left chassis is 6A8-(2)6K7-6J5-(2)77-75. The right chassis is 80-5Z3-(2)6A3-42. All tubes, transformers and the speaker are Philco parts. The tube shields have caps on them(is that the way they came originally?). This is a 3 band radio.
