M43 Howitzer Motor Carriage 203mm (T89). - Under construction !

      New projects...Time to see this huge girl, sister of M40 GMC 155mm: the M43 Howitzer Motor Carriage 203mm (T89).

      The M43 Howitzer Motor Carriage 203mm (8inches) was an American self-propelled artillery vehicle built on a widened and lengthened Medium Tank M4A3 chassis, but with a Continental engine and HVSS that was introduced at the end of the Second World War.

      The M43 shared the same chassis as the more widely produced M40 Gun Motor Carriage, which instead mounted a 155mm gun, and were designed by the Pressed Steel Car Company
M40 GMC 155mm
      A production run of 576 was planned originally, but in the end only 24 were produced and another 24 were converted from M40 hulls. The M43 went on to serve in the Korean War, and was retired after its conclusion.
M43 in firing position
      Equipped with a M115 203 mm (8") Howitzer, it was designed to replace the earlier M12 Gun Motor Carriage 155mm. Its prototype designation was the T89, but this was changed to the M43 in March 1945. The 41.5 ton vehicles struggled to keep up with mechanized formations, but were successful when employed in more stationary roles.
M43 front view
       A single pilot vehicle was deployed in Europe before the end of World War II and was used in action by the 991st Field Artillery Regiment, first seeing action as part of Zebra Force in February 1945 in the capture of Cologne, togheter another single M40 GMC 155mm.
M43 rear view
      The M43s were used in action in the Korean War, where they were well suited to the static fighting there, their high angle of fire permitting them to hit the rear slopes of hills.

The kit:
      To start this project, I used the excellent AFV Club kit (#35031) of M40 switching the 155mm metal gun barrel by the AFV Club kit (#35S-06) M115 8 inches howitzer aluminum gun barrel. 
The kits in my workbench: M115 and M40 boxes.

Same parts except the barrel.

     The kit (#35S-06) M115 8 inches howitzer was not "crippled" since I used the 155mm barrel left over from the M40 AFV Club kit (#35031) to turn the 8 inch howitzer into Long Tom 155mm gun. "In modeling, nothing is lost, everything is transformed" (First Law of Conservation of Model Stuff).

Mercedes-Benz L 4500 R Mautier with spoked wheels - case report

      I would like to show you a project (2010) of a very interesting truck: the heavy half-track Mercedes-Benz L 4500 R Maultier - SdKfz 3/5.

German heavy half-track Mercedes-Benz L 4500 R Maultier
      But that is not all. In my pilgrimages through the internet, I found this interesting photo, in the excellent site of Kfz der Wehrmacht: an Mercedes-Benz L 4500 R Mautier with spoked wheels!! I've never seen this before a beast like this !!!
Mercedes-Benz L 4500 R Mautier with spoked wheels.
This truck was photographed on an Allied collecting point for war materials.
The spoke wheels of the running gear are unusual.
These wheel type could not be identified on other photos.
      Bingo! ... That was enough to trigger a new project with the brand "Panzerserra"! 
Mercedes-Benz L 4500 R Maultier - SdKfz 3/5
spoked wheels version.
      But first of all, as usual, let's know a little more about these girls:

      The Mercedes-Benz L 4500 was a heavy duty truck by Mercedes-Benz. It was built by Daimler-Benz from 1939 – 1944 in the Mercedes-Benz plant Gaggenau and from 1944 – 1945 by Saurer. The vehicle is a long-bonnet truck and was offered as a rear-wheel-drive truck (L 4500 S) 4x2: 
MB L 4500 S 4x2 with late wood cabin and wing fenders
Notice the front axle
      And an all-wheel-drive truck (L 4500 A) 4x4. 
MB L 4500 A 4x4 - Afrika Korps
      Later, a half-track version was built, with the designation of  L 4500 R. 

      The German Wehrmacht used the L 4500 with armoured and soft cabins as Flaks during World War II.
MB L 4500 A with armoured cabin with 37mm Flak 36
MB L 4500 S with metal soft cabin with 20mm Flakvierling
      Due to the lack of production material, the cabin was replaced with the simplified standardised Wehrmacht cabin and the front fenderss with simplified wings in 1943.
MB L 4500 S - interior of Einheits cabin
Brand new MB L 4500 S 4x2 with late Einheits cabin and wing fenders
MB L 4500 A:
      The L 4500 is a truck with a long bonnet, U-shape ladder frame and both front and rear rigid axle. Each axle has leaf springs. The front axle has single wheels while the rear axle has double wheels. The tyres have the size 10.5—20. A pneumo-hydraulic brake-system is used, each wheel has a drum brake, the parking brake locks the rear wheels only. For steering a ZF Type 721 is used. From the engine, the torque is transmitted to a manual five-speed gearbox with a single disk dry cluth. The gearbox also has a reduction gear. Only the rear wheels are driven. Unlike the L 4500S, the L 4500 A has an offroad gear which automatically switches on the front-wheel-drive as well. The Mercedes-Benz OM 67/4 Diesel engine is used. It is a six-cylinder inline four-stroke precombustion-chamber-injected and water-cooled diesel engine with OHV-Valvetrain.
OM 67 - OHV Valvetrain Diesel engine - 7274 cc
MB L 4500 R Maultier:
      The German combat experiences in Barbarossa Operation demonstrated that in Russia, with virtually no paved roads, thousands of wheeled vehicles stuck in the mud and snow and were abandoned in the first winter of that Operation. Even the four-wheel drive Mercedes-Benz L 4500 A could not carry cargo on the Russian off-road conditions. Therefore in 1943, Daimler-Benz built the half-track Mercedes Benz L 4500 R Maultier. Mechanically, it was the chassis of the MB L 4500 S 4x2 heavy truck with the rear suspension and transmission replaced by a tracked suspension.

 Later, opted to used one suspension derived from the light Panzer II, for standartization.

Father and son...
      The half-track had his weight increased, the cargo capacity has dropped to 4.5 tons, maximum speed dropped to 36 km / h and fuel consumption reached 200 liters per 100km. The MB L 4500 R released until 1944, having to build in 1486 vehicles. Other reason for their production were delays in development and then production of Schwerer Wehrmachtsschlepper (sWS).

      Like his wheeled sisters, the Mercedes-Benz L 4500 R Maultier was built with metal cabins and Einheits type. They were considered excellent transporters for rough terrain, being used as cargo transporters, guns and artillery tractors.

Notice the drive sprocket is smaller than the ones in the metal cabin versions.
The end of a warrior...

My version:
      My kit was built based in the actual pic and nothing is known about why she be using spoked wheels. Much was discussed at the time of the construction of this kit (2010) which wheels were ... As it was a German vehicle, the logic indicates that they were German wheeled wheels: I opted for Panzer I spoked wheels.

Panzerserra's guidance blueprint
     Another intriguing detail: a white stripe on the engine's bonnet of this vehicle. Would she be using a piece of an old DAK vehicle ?? Or even a whole desert vehicle would have suffered a full overhaul?  Who knows ?? But my girl will wear this band, I guarantee!
Notice the white band in the engine's bonnet...

The kit:
      I used the excellent kit from Zvezda (#33603) for this girl:
Zvezda's 3603 kit - Very good!!
      And I had an old Zvezda Panzer I kit in my scrap box:
My spoked German whells option

Law of the Conservation of Matter applied to the military models:
"Nothing in your collection is lost, everything can be transformed. "
      Open the holes in the spoked wheels...

Wearing the wheels in my mini-lathe ... This vehicle was very used ...
Final results!!

       By the book, building the Maultier chassis and suspension...The kit is gorgeous!!
      As I used "scrap" wheels ( I hate "kill" new kits...), some alignment adjustments were needed. Here, making washers to adjust distances

In position...
And the links in position. Perfect!!!

adding details in the cabin...
       And my decals, made with my Lasercolorprint. The Gulf badge is for my pump-fuel...
The previous painting...
...and the decals in position!!! Good
Next step: close the cabin!!
      I have decided to use the plastic canvas that comes with the kit. I thought she looked pretty convincing ...

Now, the weathering...
       And the Mercedes-Benz L 4500 R Maultier - SdKfz 3/5 was ready.
