Hello Neil,
On my worktable right now is a Ford truck. I´m in a Finnish kind of mood at present, so it´ll be a Finnish Ford 098 truck converted from a German V3000 truck.
I´ve used the cab from a HR Models resin kit, but the chassis is from a Mac Opel Blitz. The wheels are from the Airfix GMC. The old wrong ones with 5 holes fit this one perfectly. The loading area will be scratch built.
The biggest problem right now is that i would like to make it a wood-gas powered vehicle, but i have no idea about the wood-gas system used on these. I think it was a "Svedlund" system, but haven´t managed to find anything useful on the net.
I notice that you didn´t follow my advice about using an UM kit for the Flakvierling T-34, but i´m sure it will turn out nice enough anyway.
About the Kübelwagen, as the others said the Italeri one is the most accurate one, even though it´s not as detailed as the Academy Kübel. Dragon also offers a ready-built one that looks very good. I´m sure it´s better than the Italeri kit, and i hope Dragon will release it as a kit too...
