Who cares where he got half the stuff from. Suerly if most of it is on the internet already, being seen by millions of people every single day, then to my mind, its all fair game. Mind you, I was quite lax myself regarding the copyright on some items used in "an introduction to invalid carriges, but then in some cases, I hold the only original copy in known existance! Also, david comes from Hungary of all places, where else (and what else) was he expected to find details? Peel owners in my experance are not the most forthcoming of people when it comes to clear details....
Correct me if I'm wrong also, but I belive there is no copyright at all on manufactures sales broshers or leaflets of any age, due to the fact they were designed to be given away left, right & center to all and sundery?
