This is my representation of the early opel troop carriers used by the wehrmacht motorised troops during the blitzkrieg period of the second world war.
There were basically three versions of the opel blitz 3 ton truck, the first two produced in parallel from May 1936 until early 1941 the first had wheel arches so was not suited for cargo transport the second had the cargo bay raised above the rear wheels so could be used for both troops and cargo. In early 1941 a new version was introduced with added high side rails then in late 1942 some economy savings by removing the rear mudguards, bonnet Opel logo and cab search light were introduced.
From August 1944 only Opel blitz trucks with the unified wooden cab (Einheits-Fahrerhaus) were produced until end of the war and was the final opel blitz 3 ton truck used by the German wehrmacht.

I wargame in 1/144th scale so all my models are in this scale but it's fairly easy to up-scale to what ever you want.
