There is a little known book titled The shot gun written by T.D.S Purdey and J.A Purdey printed strictly for the sportsmans library in 1936, that will indeed give you an insight into to the mind set of an upper crust limey family who at the time made some of the finest sporting guns some would say. If nothing else it is an insight in to what the upper crust sports man should know in etiquette and guns, it also has the poem The battle of the guns going through all the prominent London gunmakers one by one with just a couple of Birmingham makers thrown in.
