Sd.Kfz. 234/3 Eight Wheeled Armoured Car with 7.5cm Gun


Recommended Posts

My kit for this GB is the Dragon kit of the 8 wheel armoured car armed with a 7.5cm short L/24 gun.  This weapon had been fitted to the older Sd.Kfz. 233 armoured car and also to some Sd.Kfz. 251 half-track vehicles.

Around 90 of these 8 wheeled armoured cars were built between June to December 1944 and issued to reconnaissance Panzer Units and Panzergrenadier Divisions.

There is one preserved vehicle left in world, WH-1751008.  This is at the Bovington tank museum, but not much use as a reference item, it's not complete and has been re-painted in a spurious grey colour.

Dragon brought out all 4 variations of this vehicle during 2007 and Cyber-Hobby released a late war conversion of this /3 vehicle in 2008.  More expensive but much better detailed than the old Italeri kits.

Here is the kit, it's been untouched in my stash for 15 years, time to get it built!

Not long to the start of the GB.

Started work on the steering and suspension, the 8 drive shafts (B4) have pins that go into the hub units (D19).  If the pin is removed and the steering linkages are left off, then the wheels can pivot on the suspension arms and be positioned in any steering position.  One more pin to remove.

Suspension and steering parts all assembled onto the lower frame and leaf springs added.  These kits are really well engineered and go together without any problems.  I have started assembling the wheels, 9 of them including the spare.  There is a choice of 2 hub units with either 2 or 5 ventilation holes for the brakes.  This kit is different to all the others in that it includes 3 radial tyres, not sure if I will add all of them to this build, I might mix them into my other 234 armoured cars.

The unattached hub units are to add to the other side of the chassis, my clumsiness knocked off some of the pivot pins so I have drilled and replaced them, just letting the glue harden.

Next, I will add the lower chassis to the lower hull half, then I can start adding the interior parts.

Any comments or questions are always welcome.

Todays update, I glued the chassis frame to the lower hull, I have pushed the wheels on and angled all eight wheels to show the effectiveness of the steering.  If you are putting these armoured cars into a diorama or just gluing the wheels at an angle, the steering linkages can be adjusted for length and attached, Dragon made all the steering in the neutral position, with all eight wheels inline.

You can see the different tyre patterns but there are only three of these nice radial tyres as a kit bonus feature.

All the parts that are in base colour have been attached to the lower hull, the steering wheels have been tacked on with some PVA for the photo, it shows the two driving positions with the front one at that weird angle because of the sloping frontal armour.  The rear steering wheel has to have a cut out in the fuel tank to accommodate it.  While the other Sd.Kfz 234 armoured cars have a same internal layout the 75mm armed /4 is slightly different, there is a floor mounted frame for the 75mm gun that the driver has to crawl under to get to the driving position and there isn't a fuel tank next to the rear driving position, which is strange as the external filler cap is still in the same place on the kit. :shrug:

In reality, steered wheels should never be parallel.

I find, on a model, it sometimes pays to exaggerate the angles slightly more than they would appear in real life.

Just Mark.1 eyeball method.  In normal conditions the rear wheels would be locked into line as the driver would be just using the front wheels for steering.

Agreed, but how I have the steering in those last photos would have the vehicle turning in such a tight turn it would have the gun crew hanging on for dear life. :wtf:

Great start and looks to be a very nicely detailed kit 👍

I like the variation in the tyres...makes for an unusual look.

Is there any basis for the radial tyres? Is it to do with steering or ride comfort?

I see the box art has them on the centre axles?

There seemed to be several variations in tyre patterns seen in photos of these 8 wheeled armoured cars at vehicle collection points after the fighting had ended, I think it was a case in the last year of the war that if it fitted, it was used.  I can see that those radial tyres would have been better on paved roads but not off road.

None of the other kits in this series of 8 wheelers had those bonus tyres as an option, well, not when I bought them 15 years ago.

Many thanks for an informative thread! The steering mod is really neat - presumably if you didn't glue the pins at the top and bottom of the outer "cup" you could have moveable steering? And the interior shot clarifies a lot which is not clear from the instructions. I was wondering how the front driver got to his seat!

 

Regards,

Adrian

That's how I have done it, the friction of the ball mount and the top and bottom pins retains the wheel hub and allows it to be turned.

 

Today's update, I have attached the rest of the internal parts, mainly the visors, they are workable if you are careful with the glue. :like:  The 7.5cm gun still needs the recoil guard fitting, I will attach that after some detail painting.  I keep mentioning the unfinished armoured cars that were above the 25% rule, so I have dug them out for a photo line-up of the different versions of this series of late war vehicles, hopefully I can retain my motivation and get them finished now I have the AM and p/e that I paused their build to wait for.  (Metal barrel already fitted to the Puma)

It's funny how you forget things, on checking out the Sd.Kfz. 234/4 I found the gun compartment is enlarged further back than the other variants, so the fuel tank and its filler cap were moved, not sure where they relocated it to, it's pretty busy in there.  Also, I had forgotten that the mudguard middle stowage bins were deleted on this vehicle.

IMG_1961

Tomorrow will be time to start painting the interior so that the upper and lower hulls can be glued together and that will allow the final exterior parts to added.

Thanks for looking, any questions or comments are always welcome.

Painted the inside of hull, I used a MRP silver primer so that I can do some wear and chipping.  On top of this I sprayed Tamiya XF-88 dark yellow, and it looks a good match to the paler late war dunkle gelb.  Just needs some washes, shading and wear to make it pop.

An impressive 8-rad line-up! 😀

Nice work Bob, great info on the steering too. (Wheeled vehicles always look better with a degree of steering deflection I reckon). 

Hope to try and keep up with your build....🤞

On the parallel wheel issue, wouldn't the middle wheels on each side be angled slightly more than the ones at front and rear due to them being closer to the pivot of the turn ?

 

I hope that makes sense

 

I seem to remember reading that the steering was "differential" for want of a better word, - ie the middle wheels angled less that the front/rear ones, but I may be wrong! I also believe that the rear wheels could be locked to stay straight so only the front ones turned, but could be unlocked for tight turns and/or when driving backwards.

Erm, ask me one about Sherman tanks.
