Tamiya 1/35 Sd. Kfz. 139 Marder III
Model, Text and Photos by: Nick Cortese
History
Production started in 1941. The Marder III Sd.Kfz.139 used the obsolete Czech LT38 chassis as its basis. The actual gun was a captured Russian 7.62cm Pak 36 mounted on the Czech made chassis. Close to 350 were finally built of this particular model, serving the Werhmacht as one of its most feared Tank Hunters.
The Kit
The
kit is comprised of 5 light tan styrene sprues, which have to be the most impressive
state of the art injection molding Ive ever seen. Over 200
crisp parts, 2 figures, onepiece tracks, poly-caps and markings for five
vehicles. A 16 page instructional booklet, which also gives you tips for figure
painting and weathering rounds out the kit. Aftermarket Details included Fruilmodel
Tracks, Marder III Fruilmodel Drive sprockets and Eduard Express Masks.
Construction
Lower Hull: As per instructions, I started
with the lower hull, which consists of 6 parts. Twin suspension and side fenders
went on without a problem. I then added all equipment accessories. Wheels were
lightly scuffed with a Dremel to give a slight worn appearance. Friulmodel tracks
and drive sprockets replaced the kits offerings, although they are quite
nice representation. Once these were assembled and measured they were put aside
for painting. At this point the entire lower hull is done and put aside.
Upper
Hull: The upper hull is one piece and just falls into place. I would advise
that you paint the inside of the lower hull and front of the upper hull (drivers
gas mask cases) before assembly. Even with the hatches closed you can still
see the interior color. Before attaching the armor side plates, I filled in
a number of very small ejector knockout marks located on the inner sides of
these plates. Once the armor plates were assembled, shell racks and exhausts
were placed along with travel lock and front hatches and any smaller parts.
I assembled and cleaned up the basket with an Xacto Knife, removing tiny mold
seams, then put it aside for painting. Both seats were assembled then put aside.
Gun: The impressive Soviet 7.62cm gun barrel, breech and cradle went together
smoothly, although the cradle is in 2 parts and needed a small amount of putty.
The carriage assembly was attached along with equilibrator and various smaller
parts. Once again, the front armor plate has small ejector marks and needed
filling. Take extra care when attaching the side armor to the front. Both sides
should line up perfectly with the cruciform support (part# D29) and snuggly
fit into the poly cap encased lower hull. The fighting compartment is excellent.
Painting
For
painting, I wanted to tackle a winterwash scheme of a vehicle that
was somewhere on the Russian front, complete with mud and dust. All sub-assemblies
were carefully washed with soapy water and were prepped for painting. To simulate
the muddy underside and road wheels, a simple yet effective technique was used.
Black pastel chalk was mixed with Tamiya thinner and dabbed onto the areas representing
mud. I use black chalk because it blends right into the pre-shading technique
I started with the pre-shading method of flat black (XF 1) throughout the undersides,
wheels and in areas that would cast a shadow only. Once again Tamiya acrylics
were used throughout. A heavily thinned Dark Grey (XF 63) was airbrushed throughout,
leaving the black pre-shade just barely visible I try to keep it very subtle
here. Smaller parts such as the tools , seats ,etc.,
.where carefully picked
out with humbrol enamels. The recoil slide and breech got a coat of Humbrol
Metal Cote to give it a realistic metallic look. The actual white
wash is a slightly darkened mixture of Flat White (XF 2) , which was lightly
sprayed on., carefully letting the underlying Gray peek through in corners and
edges. For markings, I decided to use Eduards excellent Painting masks
.If
you havent tried these, I would most certainly recommend these to all.
Easy to use and no pre-gloss coating. After the markings are applied I went
back and applied a light coat of whitewash around the markings giving
a dusty worn appearance. After clean and prepped, I applied a quick coat of
Tamiya primer to the Fruilmodel Tracks, giving a good base for the paint and
pastels to adhere to. Tracks were painted German Grey (XF 63), then heavily
weathered with pastels. The dust coat, which is a very thinned overcoat of Buff
(XF57 ), starts with completely covering the underside, slowly and very carefully
creeping up the panels and sides, and on the markings wheels , giving the impression
of dust and dirt. This works extremely well, but subtlety and control is the
key to achieving proper results. I decided not to use an oil wash for this kit,
rather, figured this scheme would be a good basis to try James Blackwells
Post shading technique. Those interested in learning more about
his incredible technique can read about it here
at Missing-Lynx. A custom mixture of Black (XF1) and Red Brown ( XF64 )
was used to apply the post shading technique, just carefully spray
anywhere where oils washes would normally go, basically enhancing with paint
rather than with oils
this softens the visual impact of the
paint, giving it an almost grimy look to it
a good airbrush
is an absolute must to achieve this, along with patience
I ended with
a quick drybrushing with oils of the interior, side panels and the road wheels,
trying to keep it subtle. All subassemblies are carefully attached and awaiting
pastel weathering. Although the post-shading has done most of the
work for me, I did use pastels and kept them down to a minimum.
