T30 is for band 6 in the oscillator.
Calling this T30 is still being questioned.
Stamped with part number 51295. I don't have a parts list for the early radios that give anything other than
resistors and capacitors.
A diagram identifies this coil as "B6-S12"
Letters are for table below only.

Resistance measurements made with 4-wire ohm meter.
A to B (center tap): 0.01 ohm B to C: 0.01 A to C: 0.01
Stamped with part number _______.
NOT PHOTOGRAPHED YET
