Looking at the service bulletins for both 1940 models, the schematics are the same (except for one additional cap in the TH-14. The other components have slightly different values as well, but schematic is virtually identical.
Tube complements are also the same.
The big differences are dial plates, and wood (TH-14) or bakelite (PT-50) cabinets.
So, it appears you have a chassis out of a TH-14 or TH-16, due to he dial face.
