I did find a model number but still having issues locating the voltage in the data I found.
RAAF SIGNAL CALIBRATOR MODEL Ts/102A SERIAL # 9 A

The pictures I found look the same and all 10 tube numbers are a match. Must be an error in their data because it says NO crystals were used in this model.
Unfortunately their picture is not clear enough to see any voltage markings on the case.
