Revell Germany kit No. 07392.
Lots of detail work, including opening all louvres, separate and hinge bonnet with scratchbuilt hinges, wired engine, hand laced wire wheels to correct pattern, dash board painted to resemble timber, radiator louvres opened up.
Not perfect, but I'm happy with how it turned out. Not a factory correct colour, but I liked the look of it. Too many other models already in red.
