Futher to the thread
CMP Umbau-Wagen, here's a picture recently sold on eBay (
Item #2259320882, sold by
rwcmilitaria), showing (at least) three Morris-Commercial CS8's captured (at Dunkirk?) and rebuilt as
Kübelwagen or personnel carrier trucks by the German Army.
The conversion seems to be different again from those found on CMP F15 trucks.
