Keith, interesting shots, thanks!
A word of caution re. the DVD you hope to make with all of "your" photos of british trucks in German use. I bought an original print of the PU Kübel off Ebay a while ago, only to find it up for auction by the same seller, and published in a book. Obviously, it was not an original print, but one of many printed on old photo paper. . .
What I´m trying to say is you might want to look into copyrights before publishing your DVD.
Regards,
Hanno
