I tend to get my ideas from reference images, so here's a screenshot that I pulled off of a YouTube clip.

The base kit is the Italeri 1/35 scale Kfz.15 Horch (No. 6215) with some AM added and some minimal scratch-building.
Here’s a rundown of the AM parts:
DEF Model Horch Kfz.15 (sagged) resin wheels
Minor canvas side windows
Value Gear stowage
Tamiya Jerry Cans
Alliance vehicle dials
Scratch-building:
Left windshield (cut-out)
Interior door handles
Left fender Jerry Can rack
Fuel filler guard

Vallejo Primer: German Panzer Grey (73.603) with a touch of White (74.600) added.

PE Canvas side windows in primer: Tamiya Fine Grey Surface Primer (rattle-can).

Started Franken-figuring and dry-fitting the figures.

Canvas side windows WIP ... gotta' use your imagination for now.

Cheers!🍺
