Petr, thanks a bunch for calling out this site. Folks, this is a treasure trove of German and Allied softskins from WW2, including a number of interior shots of truck cabs, etc. These are vehicles available for movie/TV rental, and as such they are shown from several views. The list is arranged by year of manufacture, so you can do whatever period you want, but the German stuff starts on the first page in the 1930s and goes up to the late 1940s (the Opel Blitz trucks were built in their military configurations until 1950). I have bookmarked this site, and will add the photos top my collection as modeling references. Great stuff....

Bob, they have the Mercedes L3000S and both Typ S and Typ A Opels, metal and Einheits cabs, mostly in excellent (as in brand new) condition.
