[Milsurplus] Looking for AT-5, AR-8 Bits

[David Stinson]

Seeking some AT-5 parts:
I just received a very nice WWII RAAF AT-5 transmitter.
It's a very interesting and cool-looking transmitter.
I need a good outer case for it, if anyone has one
they wish to sell or trade.  There are two small plastic
windows just below the HF Master Oscillator dial.
They are oxidized.  Can anyone tell me what these orignally
displayed?   I'm also seeking original connectors for it.

I'm hoping to find the matching receiver, which
would be an AR-8 (Austrailian or UK, either OK by me).
If you have one, I have lots of trade material.

Thanks.
