For Exakta enthusiasts who don't already know, among the books that Herr Wurst wrote was the one named in the subject line - which I recently bought (Ebay again) even though my knowldege of German is strictly limited. I subsequently discovered that it was translated into English, published by Fountain Press in 1960 as the "Exakta Manual -the Complete Guide to Miniature Photography with the Exakta Camera". This book has an extra chapter covering the VX (aka Varex) lla. By a lucky chance a websearch led me to a pristine copy in my local Book Store for 10GBP. (Now if only I can find someone who would like to buy my German version !) "Googling" Werner Wurst, Ihagee, or even Exakta, as the fancy takes you - is recommended..
