Captured British truck in German service: ID wanted

[Hanno Spoelstra]

See WW2 german AFRIKAKORPS photo Crew on lorry Wehrmacht wh showing a "Group of Afrika-Luftwaffe Sodiers on a desert-wehrmacht-lorry". This is obviously a captured British truck (possibly in Caunter scheme camouflage), but what type? It go me stumped, and I don't have my references at hand to look it up. Who can enlighten us?
Note it has a German Notek lighting system and Wehrmacht (WH) or Luftwaffe (WL) registration added, which denoted it was not a temporary ride picked up off the battlefield.

Thanks,
Hanno
