Thanks. The source image eswube provided is at an angle showing both its side and stern, and given that the bow and stern are nearly identical, I could possibly draw a front view of it.
Believe it or not (well it's probably really believable since I have a habit of drawing weird vehicles), I'm actually familiar with the Lauster Wargel tractors. Sadly there aren't very many images of the LW-2 and LW-3 on the net.
ONI,
there's a free download of the (rare) book on German big-wheel vehicles including the Lausters (LW2 to LW-7s) here .......

It's in German but I'm currently having the relevant Adler & Lauster parts translated into English.
