What you could do is to take a photo of the kit hull from the same angles as the original photos and compare the rounding of the hull.
I get the impression that the kit hull is fairly accurate in shape but it is difficult to compare when the angles and the lighting is so different ...

To my eyes the rounding between the top and the sides of the hull look good.
The corners that you have marked could possibly be a little to sharp on the kit. Those should be possible to sand down to make them softer/rounder, there should be enough resin there
I also get the impression that the rear edge of the wheel arch is almost a horizontal straight line on the real ARW but on the kit it curves slightly downwards to form sort of a point.

Artyom,

Beautiful build you share with us. Thanks.

Which supplier you took for these welds?

If this is a Mannschaftstransportwagen or APC, I wonder how the dismounts get in and out?

hmmmmmmmmmmm
going off on a wild tour into the dark forests of the Guessing Country ..............

1. This was a prototype.
2. I read somewhere that the specified weight limit was to be 7.5 tons and the armour was specified as 13.5 mm
3. The rims were cast from some kind of light metal alloy to keep the weight down.

Casting something large is one thing, casting something large and with thin walls, 13.5 mm thick sides of a casting that is somewhere around 5.5 meters long is more difficult.

My guess is that the hull was not cast at all except maybe for small pieces. If I were to build such a prototype I would use steel plates. For the full scale production it might be better to use casting but considering the shapes of the hull it could still be easier to shape steel plates and weld them together. Maybe it was even a simple armoured box with rounded ends and the fancy shapes over the wheels was only thin sheet metal.
The welds you have made under the wheel arches:

would fit the armoured box theory. The flat sides is the armoured box and the rounded shapes on the outside are there to increase volume to try and meet the original requirement that the ARW should float ...
Maybe you have already seen this page:

The answer to your question: My guess is that almost the whole thing was welded. Don't know what I should say about the turret though ...

Really nice detailing work, built that kit myself, but straight from the box.

Those welds look very realistic

I admire your modesty almost as much as your skills – those weld-seams are superb, along with everything else you have done so far

That's one ugly vehicle, and it doesn't appeal to me at all, but I must say the kit looks like one superb job of casting.

For that time period the vehicle was IMHO years ahead as we speak of design.
I new the Magirus design and it's appearance in real time. Very special and very different. I like it.

Kind regards,

Robert Jan
