I don't think anything for the TRK-12 was borrowed from this design. The TRK-12 was based off the RR359B. The later ones were already using such things as the 12AP4, cardboard crt protector and rubber mask that ended up on the TRK-12.
Now the first Dumonts were exact copies of the British Cossor designs.
