https://www.createspace.com/5070216 I recently got a copy of Tom Davis Jr's brand new book on the history of British use of the Thompson SMG. This is very much a history book rather than a technical book, and it is based on meticulously researched documents from the British national archives, right down to the hand-written notes scribbled on telegrams and tally books. If you are interested in the United Kingdom's effort to supply arms during the first half of WWII or in the history of the Thompson in general, it is definitely a work to add to your reference library. http://www.forgottenweapons.com
