Sorry Tiggie, I just did a Google for "m151 military vehicle" and that was one of the dozens that came up, pity we couldnt get it again as it had loads of links. Try
www.berlin-brigade.de/vehicles/show.php but it is only black and white pics but interesting other vehicles as well as Mutts. US based
www.carnut.com has coloured restored pics, look under "military vehicles" in the index. There a few in UK owned by restoration/military enthusiasts.
