Default G&E Bradley D.C. Calibrator Type 126B

Can anyone help with info, or a service manual for the Bradley 126B DC Calibrator? A half rack width unit from the 1960s, with a +/-2.5kV DC output.

A few pictures of this calibrator, I was unable to find any information on the web, not even an magazine advert from Bradley.

A subsidiary of Lucas Defence Systems so possibly all hush-hush? Graces Guide says they were involved in VOR, radar and lasers

Well I didn't know that, I do know they made various calibrators, both DC & AC voltage/current & oscilloscope calibrators, an analog multimeter, oscilloscopes and counters.
Graces Guide states they were acquired by Lucas in 1959, the renaming to Bradley Electronics Ltd might be earlier than 1983, there is a reference to the change in this 1970 magazine https://www.worldradiohistory.com/UK...adley%20126%22 I wonder what the "G and E" stands for?
