I have the old and new Roco Opel Blitz trucks, military and civilian versions. I also have the Wiking Opel Blitz trucks but it is still nice to get even more variation, so a couple years ago I got this truck from Wespe Models.
The kit is nearly all resin with wire for the axles. The parts are pretty strong for resin and almost no flash.
The instructions are rather weak, but the parts fit together well. The cab is one big part.
