In the last issue of "Der Waffenschmied" there was a nice walking tour map of the gun maker's in Suhl. Has anyone checked it out?

I am heading to Germany in a few weeks for the Kassel Show, and am planning on visiting Suhl again for a day trip. Will visit the Waffenmuseum again, and also want to visit the Zella-Mehlis Stadtmuseum as well. So, I thought I might try the walking tour.
