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?
I may have misread your question but you can download them from the AFV Modeller website shop.
