[Milsurplus] Aircraft Wireless Set T.R. 9D

[David Stinson]

Looking for any and all information on WWII British
aircraft wireless set T.R. 9D (TR-9D), which 
consist of transmitter T-1119 and receiver R-1120.

Specifications (freq, power, emission)? 
Looks high HF.

Power requirements?

Are tubes for it available
(this one is missing two VR-18s and one VR-27)?

Can a person find a plate cap for a VR-18?

Was a power pack fitted behind the transmitter?

I understand HT+, LT+, E, AE,
but what do GB+, 1/C, and H+1/C mean?

What is this knob on the top of the receiver
that's marked 0-180 degrees and has a lock ring around it?

Anyone have a parter that has the long, thin
cover panel that goes between the TX and RX?

Any chance of finding a manual?

Thanks very much,
