I have your article "outlines the development of Germanys infrared night vision system on the m.SPW Sd. Kffz. 251 series"
Very interesting material and photos, as well as drawings. The question is, where and how I can find drawings of your article?
The wonderful drawings come from Dan Graves. He and Bill Auerbach (are I hope still) in the process of putting together the big book on the 3 ton halftrack chassis sdkfz11 and 251 series.
Dan kindly supplied a couple of draft drawings for the article but we will have to wait until they get published to see more Im afraid.
