Just to be clear, your receiver should have the pair of 6V6 output tubes at the rear in the middle behind the tuning cap cover, which location signifies a Super 12.
The two additional control shafts were indeed a late version enhancement of early 1940, just before the introduction of the Scott 14 tube Masterpiece which moved the output tubes to a larger 3 tube power supply. I had such a 6 control Super 12 with the 2 additional controls, but never got to a restoration.
Accordingly, I suspect your one tube outboard power supply should have the upgraded 5U4 rectifier (rather than a 5V4) as per a one page addendum to the instruction manual. Do your tube sockets have embossed tube numbers?
Per the addendum, the two additional controls are:
lower left: radio/phono switch
Lower right: Sensitivity.
If so, the radio phono switch was moved away from the band switch to accommodate the optional 5th band: the ultra high TV audio red band mine had.
Looks to me like your receiver chassis is missing the left rear corner coil assembly. But the two adjustment hole covers on the left middle coil can look like the early version Super 12 when the power transformer was located on the receiver left rear corner. So maybe yours is complete.
Remember, Scott was a custom set builder. Perhaps used parts on hand (older version middle can) to build yours near the end of the Super 12 production.
