I am mainly interested in Army visors but also waffenrocks. I collect reference books for my sins as well. You can never have enough books ! Bought my first piece of German militaria in Athens in 1978 and been kinda into it since then.
I have a book published on the Development of the German Army Visors from 1871 to 1945. I also have a shop at www.acmilitaria.com should you wish to browse.
