Do they exist?

I love to watch gun camera footage, but where do I find it?

yep, many of the major aviation history mags have advertisements for them, you just got to check them out. i don't know how specialized they are, such as specifying german footage or raf, if that's what your looking for as an example. more than likely it's the same footage you already see regularly on the military channel / history channel, etc.
