I suspect Birdy grew up on the other side of the Atlantic, so a couple of the names he mentions are unfamiliar. We used to watch cowboy films, but hardly ever read cowboy books. Tarzan, of course, was a favourite; G.A Henty wrote (seemingly) hundreds of 'boys own' historical adventures with titles like 'With Clive in India'; among others that I devoured were Conan Doyle's 'Challenger' adventures and (more 'adult' and 'daring') the Bulldog Drummond stories by 'Sapper' and the Fu Manchu tales by Sax Rohmer. All incredibly jingoistic and racist, aimed at perpetuating the idea that 'the sun never sets on the British Empire'. Most of them would be banned now, of course. They culminated in the 50s in the James Bond novels of Ian Fleming; Bond was above all things, the defender of British values, and would expect to be addressed as 'effendi' or 'sahib' depending where he was.
