EVBoy, I think you have a model 16A -- little brother to the 800B, meaning that it lacks shortwave and the motorized tuner. The cabinet looks like a Chippendale. See the 800B article on my website, which shows a restored 16A (not mine):

A wonderful thrift store find, in any case.
For the record, these radios were made by Scott Laboratories, as the company was known after the founder, E.H., left.
Chad, you have an 800B, with shortwave. The big square chromed assembly on the back of the tuner chassis is the motorized tuner. You are correct, the power chassis also contains part of the FM circuit. So if you have an 800B without that chassis, you can't just lash up a homebrew power supply.
If your chrome is badly pitted & flaking off, then you are looking at an expensive replating job. Typically, the pitting is worse on the cans than on the chassis itself. It would be much cheaper to replate only the cans and the RF cover and leave the chassis alone. I shudder to think about stripping that chassis down to bare metal and remanufacturing it. If you do that, I'd suggest taking a million photos and even drawing some pictures, so you could replicate the original lead dress, etc.
That cabinet doesn't look right for the projection TV model, where the right half of the cabinet top flips up to let you raise the projection screen.
Your photo doesn't show what's behind the left door. Look at the photos of my Scott radio/tv/phono combo at:
http://www.antiqueradio.org/scot03.htm
In that set, the direct-view TV is in the right compartment and the tuner is on the left, with space above to hold the record turntable, whose lid flips up.
Perhaps your set was a radio/tv/phono combo, with a missing TV, or a radio/phono combo.
Scott gave people lots of options, with different cabinets and components, or no cabinet at all. I have been told that the postwar radio/tv combos came with a variety of TVs, manufactured by different companies, and ranging up to 19" CRT size. I have spent years trying to identify the manufacturer of the TV in my combo.
