Scammell Pioneer SV2S Heavy Breakdown Tractor - case report

Hurrah!!!
      Finally, after ages in the modeling, I will have the opportunity to build this tractor, without undoing a cornea or a kidney (very important parts for my shabby body kit ...). Let's build the Scammell Pioneer, in the version SV2S Heavy Breakdown Tractor.

The Desperate Girl!!!
    My dreams have come true: We have the Scammel injected at our disposal. Praise be to you, beloved IBG Models, who heard our prayers and supplications !!!

History:
      The Scammell Pioneer was a British 6x4 tractor unit used in the Second World War as an artillery tractor, recovery vehicle and tank transporter.
      Designed as a 6×4 off-road vehicle for use in Britain's colonies where sealed roads were scarce, the Pioneer was first produced in 1927. Though lacking all-wheel drive, its combination of a suspension with great travel, excellent traction, and a low-revving engine gave it impressive pulling power on rough ground at low speeds. Though not designed for military use, the British War Office purchased a single petrol engined example in 1932.
    Equipped as a tank transporter with a permanently coupled 18t semi-trailer, it was assigned to a training unit but did not initially catch on. Additional transporters were not purchased until 1937.

      With the exception of the single 1932 tank transporter, all Pioneers purchased by the British Army were equipped with a 102 bhp Gardner 6 cylinder diesel engine, driving the rear wheels through a constant mesh gearbox and fitted with a power take-off driving a Scammell winch.

Artillery tractor:
      Introduced in 1935, the Pioneer R100 heavy artillery tractor was used throughout World War II to tow medium and heavy artillery pieces, it had accommodation for the gun's crew, tools, equipment, and ammunition.

       Typical early war use included towing such medium pieces as the 60-pounder, 6-inch howitzer and even the 4.5-inch gun and 5.5-inch howitzer until the AEC Matador 4x4 artillery tractor was issued in sufficient numbers.

      Heavy artillery pieces towed included the 6-inch gun, 8-inch howitzer, 155 mm Long Tom and the 7.2-inch howitzer.

      Many Pioneer gun tractors were lost in France in June 1940 with the evacuation of the BEF, either destroyed by the withdrawing troops or captured by the Germans.

Indeed, German loved the Scammells!!!

     Scammel produced 980 Pioneer R100 heavy artillery tractors by the end of the war, never available in sufficient numbers, the Pioneer was supplemented by the Albion CX22S heavy artillery tractor from late 1943.

Recovery vehicle:
      From 1936, the British Army began to receive Pioneer heavy recovery vehicles. The first 43 delivered were designated the Pioneer SV1S and the Pioneer SV1T both with a 3-ton folding crane and lockers for recovery equipment and towing bars. Most of these early Pioneer recovery vehicles were lost with the BEF.

      The Pioneer SV2S had a simpler redesigned extending crane that provided greater lifting height, introduced in 1938 the SV2S would remain in production throughout the war, a total of 1,975 were built by war's end.

      Among the Pioneer's equipment was a pair of tracks that could be fitted over the two rear wheels, converting it temporarily into a half-track and giving greater traction on soft ground. See in this movie about Scammell Pioneer recovery operations below, in the final images, the use of the tracks in the tractors.

      The last Pioneer recovery vehicle was not retired from the British Army until the 1980s in Belize.

Tank Transporter:
      With the exception of the 1932 prototype, delivery of a production variant tank transporter did not begin until 1937.

      The production variant was equipped with a longer chassis for an extended cab to accommodate the tank crew as passengers and larger rear wheels than the Artillery tractor and Recovery vehicle variants and was given the designation Pioneer TRCU20. 20 and 30-ton (Pioneer TRMU30/TRCU30).

      The tractor/trailer combinations were delivered, in both cases the trailer was more-or-less fixed to the tractor and not demountable like modern semi-trailer trucks. Hinged ramps were used to get the tank onto the trailer, which if immobilised could be pulled on with the tractor unit's winch. See in the movie below (no sound). North Africa 1942.

      Pioneer tractor/trailer combinations proved too tall to carry higher profile US tanks under some British bridges, resulting in their being superseded by the American Diamond T tank transporter from 1941 on.

      Despite this it remained in production throughout the war, with 459 being produced. As a result of their tall profile the trailers proved undesirable postwar and most were scrapped; the tractors were retained for use with other trailers or sold into civilian use.

The kit:
      The pieces come in a sturdy cardboard box, with the trees of pieces packed in individual bags.
      The instruction booklet is complete, with clear images, with images exploded and mounted side by side, which greatly facilitates the understanding of the assembly. The kit comes with a great photo-etched sheet, too.
Instructions booklet

      Well, let's go. Starting by the book:
Wheels!!  Injected, thank the Gods!!

Big wheels, indeed!!!

Metal and plastic togheter
       The engine is very well injected, but is a bit poor in detail. As I'm going to build my big girl with the sides of the engine bonnet open, I need to detail the engine a bit more ...
Installing fuel pipes... cooper wires.

Injection pumps in position

Using spare parts of PE and other materials ...
      First steps ready. The kit is very fun and easy to build ...
Fuel tank, external rack, engine and radiator done!!

The rear transmission assembly is built under a careful alignment ...

The radiator in the chassis...

...and the chassis winch.
      Installation of some more scratch details on the engine:

      While the dry engine, we end up to assemble and paint the chassis:

      While we wait to dry the paint and the chassis glue, we will attack the cabin ...
Cabin's rear panel: cabinets, seat supports and levers ...

Glued in place...

Cabin's floor: levers and pedals.
exchanging two fragile plastic levers by
two clothes pins. Much better!!!
       The fuel tank features two very thick plastic steps. I'm going to change both by steps made with PE leftovers
The two thick steps. Amputation!!!

The new metal ones... Much better
Notice the chain in the fuel cap!!

And the cabin glued in the chassis...
Uops...I forgot the water pipe between the engine and the radiator ...

Water pipe in position!!  Ufff!!!


      And the building continues: Time to assemble the steel cable on the chassis winch. The cable will exit through the front guides.
Waxed wire that will later be painted in black-matte.

The steel cable in the front guides...

Painted in black: the wire turns into metal...
       The cargo bed winch!!!




I was almost forgetting the air filter ... I added some metal details ...
      I decided that my girl will be painted in ETO colors: Normandy rules!!!!!
ETO colors...


 The kit comes from the factory with an excellent sheet of decals with many options, but I'd like to make my girl in the colors of the glorious 79th Armored Division: The Funnies of Hobbart !!!
79th Armored Division badge
      I researched and discovered a Brigade Workshop of the Royal Electrical and Mechanical Engineers (REME), which served under the 79th AD. I made this color guide to make it easier to place the markings...

      I had a dry-transfers sheet from Archer, with the 79th AD badge. But it is complicated to apply a dry transfer on tight, curved surfaces, such as the front of the front fender. Turning a dry-transfer into a decal is easy: just apply the transfer over a transparent decal sheet and then apply as a normal decal.
The dry-transfer turning in regular decal...

79th Bull head!!!
       Applying a variation of the Mickey-Mouse cammo:


Future to prevent silvering...
       When the Future dries, time to paint the wheel's nuts: internal white ... external red.
Whell's nuts colors...

In the kit...

Markings: 79th AD!!!

Instrument of fuel level ...
Hmmm ... Kojak needs to fill the tank !!!

Adding resin stuff: Value Gear!!!
Testing the positions...





       And the girl was ready: Scammell Pioneer SV2S Heavy Breakdown Tractor. 79th Armoured Division (Hobbart's Funnies) - 30th Brigade Workshop (Special) - Royal Electrical and Mechanical Engineers (REME) . Normandy, 1944.

      Well, thanks for following!! The Scammell kit was an old dream and I really enjoyed building this beauty !!! The IBG kit is very good, but needs a few scratch touches to increase detail. but it builds very well and it was a delight to develop this project. I'm very happy with the results...


See you soon!!!
