Hi Marc,
That model number does not show up in any data that I have. You also say that the bottom part has a 35 tube. I am guessing but if this radio has an upper and lower chassis, the bottom would be the power supply and should use a number 80 tube, not a 35.
My suggestion would be to look at the schematics for the early SM’s that use those tubes. Possibilities would be model 35A, 36A, 32A
etc. There are several that use those tubes and you may find one close enough to help. You can download the PDF’s from Nostalgia Air.
SM often sold just the chassis and and someone may have added the cabinet and the phono, either commercially or home assembled.
Good luck with this radio.
Ed.
