NAA pics
 

I can see a 19 set

Looks like a Phillips TA101 signal generator in the first image, at top shelf middle.

Yes
 

Well spotted !

I had two of these signal generators, made by Philips Australia during WW2. Designed for army field use, the power source was a 6V ( possibly 12V) wet cell battery. A basic signal generator but better than nothing if you needed one.

Philips, the famous Dutch electronics firm, had a manufacturing facility in Australia from the 1930s til the 1970s. During WW2 Philips Australia also made the receiver No.4 for the Australian army. link: https://www.radiomuseum.org/dsp_hers...ompany_id=8889


The chap sitting at the table: there is a No.19 set, plus next to the 19 set is a US BC-211 frequency meter. The BC-211 was made in large numbers , a high precision piece of kit, some were used by the Australian army. At the end of the table is a 19 set remote control unit. The white microphone is strange, looks like a 19 set mic has been stuck into a length of tubing !

The last pic: I can see the Aust. pattern battery boxes with their lids open, on the front are two power lead sockets, a Niphan socket plus what appears to be the socket for the two pronged Australian type plug for the WS 101 and FS6.

I guess the shoulder patches would read: ROYAL AUSTRALIAN SIGNALS I think there was a different colour for each branch of service ? Black background - artillery was red I think

Are those interior shots of a building or vehicle body?

I would say a building David.

Find
 

Picked up one of these recently, so cheap I had to save it. Looking for documentation. On the top the prominent ' D^D ' marking can be seen.

Quite a heavy piece of test equipment. My back is complaining. This one has the 6 Volt DC / 240 AC power supply. Army required the DC supply for field use.
