1/72 Ostmodels KV-5

t2krdf8

I wrote a review of this model on Armorama; a lot of the introduction is plagiarised from there. The first time I learned about Ostmodels was when I was browsing Henk’s Military Modelling website. The company is based in Australia, and is focusing on a niche of AFVs neglected by other manufacturers. Their models are designed for both the modeler and for the wargaming market. You will find experimental tanks, paper panzers, or tanks manufactured by smaller countries (like the Nimrod AAA tank). It is a very small company, and models are made on orders, so you have to wait if you fancy any of their products, but the wait is definitely worth it. Not to mention it’s nice to know that the model you bought was made for you especially. (And it’s not as if most modellers did not have a couple of boxes in our stash to finish, anyway…)

There is precious little information available about the KV-5. Planning of the tank (Object 225), based on the experience gained with the KV-4, started in 1941. The planned role of the tanks was to act as a break-through tank; this lead to some unusual features in the design. The hull was relatively low (less than a meter high), which meant that the driver and radio operator/machine gunner needed their own separate turrets/compartments to sit in. This also provided the driver a cupola with a good field of view even buttoned up. The three-man turret was very big and spacious, with a turret ring diameter of 180 cm, and contained a 107mm gun. (And judging by the size, possibly a book shelf and a kitchen top.) The whole tank was heavily armored (which was needed for both the intended role, and for the fact that the tank had an enormous silhouette presenting a tempting target), and weighted about 100 tons. Due to the lack of adequate engine to move this much metal, the vehicle had two parallel V-12 engines mounted as a power plant (which accounts for the unusually long chassis). Because the siege of Leningrad necessitated the increased production of heavy tanks of proven design, experimental work was suspended in the Kirov Plant to build the KV-1. Since the Russians did not seem to share the fascination of superheavy tanks with the Germans, focusing on the production of the more practical, lighter, more mobile medium tanks instead, the KV-5 project was eventually cancelled.

The kit is packaged into ziplock bags, which is enough to protect the parts from breaking. It consists of about 120 parts of light polyurethane resin.

The build was actually quite pleasant once I was done with the cleanup. The cleanup is tedious, though. Fire up your favorite DVD or TV show, get a scalpel, and start removing the thin film around the parts.

As with the SU-100Y the painting and weathering was somewhat of a protracted process. When I first worked on this kit I did the basics relatively well, but then I ran out of steam so I declared the model finished, and put it in a display case. From there it was looking at me accusingly for almost three years.

So the first stage I used a grey primer, and the hairspray technique to produce chipping on the following green coat. As usual yellow and brown filters were used to give the tank a bit more interesting look (a single hue green does look boring), and slapped on some brown filters as mud, and that was it.

A couple of months ago I got myself together and took it out of the display case again. I blended a lot more oil colors with the surface; it essentially meant I was “massaging” small amounts of oil paint with a dry brush. Since oil paints are somewhat transparent, the effect is pretty interesting and -more importantly- realistic. (As you can see the overall hue of the tank changed quite a bit.) One very important thing before you do this, though: make sure you put some oil paint onto a cardboard surface for about 30-60 minutes, so the linseed is removed from the paint. This ensures it will dry flat. (You can also buy specialized paints for model builders which do dry flat straight from the tube.)

I used dark brown washes on the pigments representing mud to make their color a bit more realistic and varied; I also added some more using the “add and remove” method and AK’s earth effect product. I added dust (using Mig Ammo’s washable dust product) and some oil stains, again with AK’s product. I used some black washes on the engine deck grilles to bring them out a bit more, and finally declared the tank finished -again.

1/72 Ostmodels SU-100Y

img_0008

One look at the SU100Y and you realize that the designers wanted to send a message: Mother Russia does not do subtle. It’s essentially a metal house on tracks and a huge gun in the front. The internal volume suggests that besides an engine and some space for the gun and ammo, the Soviet engineers managed to fit a sauna in for the well-being of the crew.

Looking at the sheer size of the thing, one would be forgiven to think it was only a paper project, but a prototype was actually built and even used in battle.

The basis of this vehicle was the T-100 heavy tank prototype, which was a multiturreted heavy tank designed in the late ’30s. It failed field trials miserably in Finland; however the hull was still useful for other purposes. After the experience of the Winter War, and the difficulties of destroying fortifications, it was realized that large caliber assault guns were needed to overcome fixed defenses. One –more successful, but that does not say much under these circumstances- such vehicle was the KV-2. The other, finalized design was the SU-100Y, which was essentially a siege-gun, mounting a 130mm gun. The vehicle went through a couple of design-phases with different superstructures and guns, but the main idea remained the same. The final version had the 130 mm naval gun (B-13-S2) stuck onto the chassis of the T-100, and was intended to demolish fortifications encountered during the Winter War. The large casemate structure is a result of necessity: it was the only way to make the ammo handling practical. Considering the size, the armor was paper-thin; this, coupled with the enormous silhouette made the vehicle especially vulnerable. It arrived too late to take part in the hostilities in Finland. The sole prototype, however, got its chance to fight during the defense of Moscow (and -despite its size and lack of armor- it survived). Fortunately it was not scrapped, and today it can be seen in the Kubinka Tank Museum. (Other sources say it did fight in Finland; I do not have access to Russian documents, so it’s difficult to know for sure.)

 

Ostmodels offers both the SU-100Y and the T-100. These kits are made for order, so you will have to wait a bit before they arrive, but the wait, I think, is well worth it.

The SU is a relatively simple model. The whole chassis and superstructure comes as one part, the gun mantlet and gun come as a separate part, and finally the running gear and tracks. Essentially that’s it. The bag consists of quite a lot of parts, but most of them are the road wheels, suspension arms and track sections. The basic construction is quite simple. While it is quite tedious to attach each road wheel to its suspension arm (more on that a bit later), it makes it possible to depict the vehicle on an uneven terrain.

All of the parts were packed into two Ziploc bags, with a small leaflet. There are no instructions included with the kit, but the construction, as I mentioned, is straightforward.

The detail in general is good and sharp. The gun is reinforced with a metal wire, which makes sure that it will not warp or break easily; I found this solution by Ostmodels an especially nice touch. The road wheels come as one unit (every wheel was made out of two wheels attached to each other). This means that the groove between the two halves needs to be cleaned up, as there are bits of resin there. The detail on the rubber tires is somewhat soft.

Due to the casting technology, there is a very thin film of resin attached to every part, which makes cleanup a very tedious process. (However no need to saw gigantic resin plugs, which is always a plus.) Once clean-up is complete, the build itself is very simple, although not without challenges. Well, one challenge, to be fair. The suspension arms are somewhat of a weak point of this model. Their ends are supposed to fit into their respective holes on the lower chassis, but this fit is way too tight; either the ends are too thick –or the holes are too small. There are no locator pins, which mean the swing arms can be positioned in any position (you can depict a vehicle on an uneven terrain, a vehicle with broken torsion bars. However, if you plan to depict the vehicle on a flat surface, then you are probably better off building a small jig that helps you position them accurately and evenly, as in the case of the Miniart SU-76. This jig would ensure that there is an even distance between the hull and the surface the model is standing on.

It’s also probably wise to insert small wires into the attachment points to make the joints more stable –and also flexible until you set the arms into their correct positions. Putting some support between the hull and the other end of the arms (where the wheels are, and hence they cover this support) is also probably a good idea, as the model itself is quite heavy. I used strong two part epoxy glue to fix the arms into their place, and small pieces of plastic to reinforce the whole running gear; if you are careful, it is not visible unless you turn the model upside down. (The wire idea came way too late in the building process, and the whole setup is a bit wobbly.)

Using online references (mainly the photos of the vehicle), and the included technical drawing, the location of parts is easy to determine. The tracks are provided as short, straight sections, and you will need to warm them up with a hair dryer or hot water, to make them soft enough to be wrapped around the drive wheels and idlers. There really is no more to say about the build –once you glue the road wheels and tracks on, you are done. The large, flat surfaces offer a lot of opportunities for weathering; the model is about the size of a 1/35 panzer I.

Painting happened in two stages with about three year between the stages… The black primer was followed by a usual Russian Green Tamiya paint, and then some filters -both as solution (about 5% oil paint suspended in 95% white spirit), and as dots. (Different oil paints dotted onto the surface and removed with downwards brushstrokes using a wet brush.) I used MIG’s dry transfer set for the slogan on the side. The mud/dust application was not the most convincing one, I have to say.

Not long ago I took the model out of the case, and gave it some more love. The sides and top received a bit more treatment using brown/yellow oil paints; I carefully and gently blended the paint with the base green, producing a bit more interesting surface. I also used brown washes on the mud deposits, making them look a bit more realistic.

Mig Ammo’s washable dust was applied onto the top in a very diluted solution; when it dried it formed a very discreet, very subtle and uneven dust layer.

I guess the point of this post (apart from showcasing a rare tank destroyer by a relatively obscure producer) is to demonstrate that it’s worth going back to older builds to improve them. If nothing else you won’t feel bad experimenting on them, and in the best case scenario they will be significantly improved.
