guys, guys, hang on a second... here are two videos I found:

the curious thing is that when moving the camera back the reticle will look to increase in size, but when zooming out it will stay the same size..
I wonder if it's a camera thing then.. Last time I lit up the GGS gunsight I have to show it to a friend I vividly remember how the perception of the gunsight reticle was the same, the only thing changing was the clearance around it. It's like saying to watch the same image through a camera diaphragm that opens up when you move closer and gets narrower when you move back, but the reticle size stays the same. I will try my other RAF gunsight at home over the weekend and will let you know (and possibly make a video too!)
Uh and the pads were not meant to allow pilots to put their face on it, they were just crash pads.
