Thanks Duke and everyone else. Some good points given by everyone. I am working on two different aspects of the assassination, Robert Oswald and possible military inteligence photographers, (including Powell and possibilly one other).
It is very useful to know what people think is the best evidence in this very complex case and i thank you all for answering my question.
Yes Lee im very well thank you, we will have to get together and have a chat, maybe over a bevvy mate.
