I got an email from a fellow a few days ago asking if there is a good book out there on the Vickers gun, so I figured it would be a good time to do a review of Dolf Goldsmith's gold standard work, The Grand Old Lady of No Man's Land. The good news is that it covers pretty much everything you would want to know about the Vickers in all its iterations...the bad news is that it's very difficult to find these days. Any price under $200 is very good, and worth buying at. http://www.forgottenweapons.com/book-review-the-grand-old-lady-of-no-mans-land/
