Sound like an interesting read! Maybe you could upload a photo of something interesting?
They probably have information and illustration's that cant be found in other publications of the time, albeit even today.
If I was in your position, I would contact the likes of the IWM and just ask... The beauty of this is that they might be scanned and archived digitally for future generations to peruse if they were so inclined.
Thats what I would do anyway.
Its interesting that spotting has a documented history, but then again, spotting is no doubt as old as aviation itself.
