Hobby Boss Sdkfz 221

The kit looks good, but the painting directions are a problem. I assume the interior is supposed to be Elfbein rather than white, and not painting directions are given for the engine. I learned the American jeeps and trucks were entirely painted in olive drab due to they way they were constructed, Same story with the German armored cars too?

Elfbein for hull interior.
Satin black for engine.

This is as close as one can get, the former Littlefield collection’s 222;
