Phil, beautiful set and nice to know other sets use similar knobs. Jim, PM sent.
The chassis are aluminum which account for the lack of corrosion. They should clean up very nicely
I careful cleaned around a stamp on the tuner with e q-tip and can just make out "Meck" and "TT10007". The tubes are 6J6 and 6AG5.
I see they used RCA components and design in the sweep circuits. That includes the typical flyback, 5V4, 6BG6 and huge power resistor used the 630TS, Admiral 30A1 and many other sets.
It looks quite primitive under the chassis.
I just noticed "SAMPLE" is written on the chassis
