This is another of the few books which deal with the Swiss CDK LTL-H Tank (locally known as Panzerwagen 39 or Praga). The author describes detailed the process how the Swiss got those 24 tanks plus 1 prototype (which went back to the factory). You will also find some "in action" pics (however most have been published in other Swiss books). What you won't find anywhere are colored sketches (sideview) of the different camo paintings the Swiss army applied. In the back of the book are also pics of surviving LTL tanks (eg in Thun or Solothurn/Schaffhausen).Thanks good, the book is written in English, not just in Czechoslovakian ;-)Overall, if you wanna know more about the Swiss Praga tanks, that's the book to get.
