I don't suppose anyone here knows how the gauges of these ac were illuminated at night?? Radium? UV? Combo?
Nope none of that fancy stuff, just a simple red lamp or two shining on the panel and on the cockpit generally.
That was really it?? Seems primitive compared with some USA ac?
Afraid so and it was very basic compared to some but not all US aircraft, the reason was basically electrical systems. I have flown that era of aircraft and the cockpit lighting was woeful with one red lamp on the panel, a good hand held torch was mandatory if you wanted to see anything and as an emergency lighting system. The next step up was to put little eyebrow lights on the instruments, you can see these in the C-47 and a lot of other aircraft. Background lighting and internal instrument lighting followed later. There was an idea about that you saw better at night with a red light not a white light, but this actually is not true, so red lit instrument lighting has basically disappeared. There was also another important aspect minimising light glare that could be seen from outside the aircraft which was important in combat at night, one little light can be seen a long way at night, basically in a completely dark night you could see a match being lit from 20,000 ft.
This era of aircraft were all pretty simple and uncomplicated electrically and generally electrics were only used where you could not use a mechanical lever or cable-pulley or hydraulic system. Most instrumentation was barometric, gyro or vacuum driven so no need for electrics. If you look at the Lancaster and a lot of other types of the period for example you will see the pilot controlled no radios, no radar and no bombing equipment, this was all done at the crew stations for that activity, all they had was a simple intercom system. Magnetos are not electrical per se but a simple magnetic system to generate a spark at the plug, the switches in the aircraft basically are wired to the ignition circuit to test the dual magneto and to break the circuit or turn it off, hence you could hand start most engines one way or another but really big engines meant a hand crank was hopeless and so starter motors would be fitted.
US aircraft really changed that with the use of multiple electrical systems in aircraft (Boeing in particular). In WW 2 electrics were primarily for radios, radars and bomb dropping equipment, especially in British aircraft. Part of the design approach was also to use an external power source, like a starter cart which then was plugged in to energise the aircraft and get the engines started, once a generator was online the cart would be disconnected. Some even used cockpit mounted cartridge guns where you stuffed in basically a big shotgun shell and fired it off to spin the engine. Another things was all this early gear was bulky and heavy (look at a 1940's radio compared to a transistor radio and now digital) and space and weight was always a premium issue in any aeroplane. Radio gear for example could take up the space of two people at the back of a cockpit with big metal racking to hold it all. The rest as they say is history.

So I suppose that means we are back to a couple of small red lights. Has this been done as IIRC we have had something like this before. Now how this would go with Ankor's Shaders I don't know.
