Finally, it's beginning to look like a Krupp Protze! I've added the cab and hood assemblies as well as the rear compartment and rear axles to the main frame. The windscreen is molded in clear plastic and the glass areas have been masked-off for painting. The stubs extending under the driver's and passenger's seats are for the spare tires (one each side). Still to be added are the real fiddly bits: headlights, width indicators, pennant frame, and mirrors. The observant among you will notice that I still have not decided how to handle the broken shovel mounted at the left rear: model it as broken, re-make the handle out of plastic rod, or remove the shovel all together. Time will tell.
Here's a photo of the undercarriage at this point:
The photo ably points out that there are ejector pin marks on the underside of each fender that will need filling. Doh!
