[Racal] Strange Racal set

[Alan Tasker]

I have a tubular frame that mounts a TRA-967 transceiver, a TRA-970 power 
amp, an MA-972B ATU, a small junction box, and a (missing) battery box. The 
battery box would be about 13.5" long by 3.25" wide by about 4.5" deep. The 
box would have two mounting screws about 9.25" apart.

Does anyone have a clue on a Racal designation for this assembly?

Is there any source for the battery box?

Thank you. Alan WA1NYR
