Hi Bahco, if you are able, get yourself over to Duxford, in Cambridgeshire. It is the "outstation" for the Imperial War Museum, and houses at least two great aircraft collections. They have their final flying day in October, and on those days, there are numerous stalls set up selling hundreds of prints and pictures of all manner of aeroplanes suitable for your needs. Apart from that, you will get a great day, and see lot's of Second World War types actually flying - Magical.
