Cool, Jean-Louis! Nice job going, there, friend!
These little armored cars are among my fav general AFV modeling subject for, oh, only the past 50 or so years! And this one, in particular, grabbed my attention when it came out.
HB's 223 is, IMHO, a pretty nice kit in many ways - full of details in and out, lots of modeling pleasure for your modeling money, goes together pretty well in most aspects, and an interesting subject, to boot!
It is, however, a bit of a "curate's egg", as some might say... HB got a lot of things screwed up in this kit. For those interested in model "historical accuracy"... The kit builds a later-war hull (actually, the last 222 hull version built - from later 1943 - by Wegmann, so, hull-wise, an "Ausf B") - but provides the early-war-style frame antenna on the early-war mounts (which, alas, were not used on the Ausf B hull). And inside, HB just simply blew it badly. Who would think that a dedicated radio car should have some radio equipment inside, right? Not, I guess, HB! The interior is very neat and full of bits and pieces, but pretty much almost completely wrong.
The real deal had a lot of radio stuff - mounted in racks behind the driver and on the hull floor and left wall. The kit provides nada. The real 223 had a crank-and-gear system to raise and lower the antenna from inside. But this gear shifted positions from earlier versions to the later Ausf B: located behind the rear cabin bulkhead in the Ausf B, and located across the cabin roof behind the driver's seat in the earlier versions / Ausf A specific hull. The kit provides neither. The later car (this kit) had a gas-filler pipe located inside the cabin on the rear bulkhead - beneath a small hatch in the screen roof. I think, IIRC, that the mesh PE does have that hatch, but no filler pipe is provided inside. The rear floor is lacking the central hump and the 2 gas tanks, and there is no jump seat provided for the radio op (but hey, no radios, so...!). The list, sadly, goes on.
I've built this one, and I tried, with more success in some aspects then in others, to correct some of the errors. Lots of fun!
But it IS a cool little build, and looks quite interesting when done, regardless. It's always neat to see folks do one of these up, IMHO! I'm pleased to see it going along, and look forward to what you end up with!
Cheers! Bob
