Interwar Tanks

One of the books I found on my shelves whilst I was searching for sources to add to my Interbellum website was THE FIGHTING TANKS 1916-1933. It was published in 1933 and its authors were Major Ralph E Jones (Infantry, US Army), Captain George H Rarey (Infantry, US Army), and First Lieutenant Robert J Icks (Infantry Reserve, US Army). Besides containing lots of interesting data (including the approximate numbers of tanks in the World's armies) and photographs, it had a diagram that showed the comparative size of several different interwar tanks.
