'A' alerted me to the above book on EBay - 'Shambattles - for boys of all ages' , it was on sale with a American bookseller and I got it for a very reasonable price . I have been aware of these rules for a while and was interested to see them 'in the flesh' , they are very simple rules which involve drawing maps and then manoeuvring toy soldiers about to capture the opponents city . It comes in three levels of complexity - Lieutenant, Captain and General , it was published in the U.S.A. in 1929 and seems to be a half way house between H.G. Wells and Featherstone , it uses a six sided spinner instead of D6 and artillery templates for firing guns , combat is based on scores on the spinner . The rules are I believed reprinted in one of John Currys 'History of Wargaming' Project books.
