I'm looking for a good newsagent in or around London which has got a good selection of magazines covering our interests (Great War, tanks, vehicles etc.).
Not really many magazines that cover WW1 available (struggling to think of any that cover it really, Britain at War and a few military vehicle/aviation ones) but for books and magazines, best bet is the Ian Allan shop at Waterloo, not far from Imperial War Museum, as well as Foyles near Tottenham Court Road tube station
