A nice choice of a firearm to read about! Now, of course, I am an unbiased person here, as it is one of my favourites plus it originates from my country (well, the previous incarnation anyway). Back to the topic at hand though. I would be more than glad to translate the book for you in order to share the information about this nice piece of weaponry.
PS: We like to call it the Czechoslovak legend that never gets old. Just a little tidbit I felt like sharing.
