I have posted some Photos of my copy of Der Weiss Kunig. This book can be found. It is somewhat rare, but I found my copy by using abebooks.com , I am sure that other sites, like bookfinder.com will produce the same results. This is a 1985 reprint of the 1775 edition. I was fortunate to find a copy in almost unused condition. There is also a book about Urs Graf, the Landsknecht cum artist. Again this was found on abebooks. The stuff is out there.
