So if my choice is to try and find all of the 4 volumes of Still’s Luger books for $1500 or The Borchardt and Luger 3 book set by Gortz and Sturgess for $300, which should I get? Assuming it will take me quite awhile to find $1500 for books. I have been loaned copies of Stills books and they are fantastic! Is the other set as good? Or a different animal completely?
