Improving the Pit-Road Russian B-4 M1931 1/35 scale

By Patricio Delfosse  

Impressive as is, this howitzer must be among the first places of an endless lists of classic weapons of Second World War. Its big caliber, strange tracks and its participation in the famous film about the fall of Berlin in 1945, are their letters of introduction. However, it went unnoticed for the most well known injected plastic kits manufacturers. Just the resin kit companies had it in their catalogue, but so pricey as the howitzer itself.

Impressive as is, this howitzer must be among the first places of an endless lists of classic weapons of Second World War. Its big caliber, strange tracks and its participation in the famous film about the fall of Berlin in 1945, are their letters of introduction. However, it went unnoticed for the most well known injected plastic kits manufacturers. Just the resin kit companies had it in their catalogue, but so pricey as the howitzer itself.


This is my seventh attempt at building a kit of this towed gun. Pit Road (old white metal kit), MB Models, Wespe, FInemolds, Minotaur and Alan offered several kit releases of this howitzer in different materials. All these kits have their pros and cons, but they are not recommended for inexperienced modelers. Having a B4 among your collection had become a difficult reachable goal, this was only for very experienced modelers and huge budges.

The arrival of this new Pit-Road kit changes drastically this concept. Apparently, anybody can have now, a B-4 in his/her showcase with very little effort and at a reasonable price. By seeing the sprue parts, we can say that none of the old kits is better than this Pit- Road one. It seems that today, having a B4 is possible.

But don’t hurry, let’s see what we’ll find inside the box.

The kit

The mold is exactly the same as Trumpeter’s which finally released for worldwide distribution their boxing of the Soviet B4 Model 1931 203mm Howitzer which first appeared back in May as a Pit Road boxing for Japan only. The difference between both versions is that the Pit-Road kit also includes a set of 5 crew figures that will be released as a separate kit by Trumpeter (plus two more figures even though to operate this gun, it would be necessary 15-16 crew members).

At first sight the box includes good injected moulded parts in the usual light grey plastic very well detailed, individual track links and a very small etched set. As my intention was to represent it in firing position, I didn’t use the transport limber.

This Pit-Road version could be considered more appropriate for the pre war period since it includes the limber with solid disc wheels seen before 1939. During the WWII, it was usual to see it with spoke wheels. (and in the 50’s they started using conventional wheels with tires)

Perhaps in the future we’ll see the long barrel (4915mm) version or even the 152mmBr-2.

There’s not any injection plastic kit available proper to tow this gun. The options could be the prewar soviet artillery tractors Kommunar and Kominter or the Stalinetz S-65 and Voroshilovetz if we want to consider a 1945 theatre. Also it could be towed by some Caterpillar D6/D7 which origin is North America.

Step 1

From the first step, we see that we’ll have a great clean up. Each part must be carefully treated to remove small defects. The mold seams are not very prominent, but should be removed from each part with a sharp edge of a cutter. It’s not a complicated task, but somewhat tedious and the assembly takes more time. A proper cleanup will assure us an assembly without complications.

Realistic wire wheels for 1/12 scale motorcycles One of the biggest challenges for a modeler who builds motorcycles in 1/12 scale, is to modify a wire wheel and make it look realistic; specially without having to buy an aftermarket kit. Anyway, there are no kits for this kind of modification (except for one of the Acu-stion for the Tamiya XV1600 kit), so it's not possible to get one. So any modeler attempting to do this task must rely in his/her ability in order, to get a good result.

Advanced techniques: Building the P-51D Mustang "Lt Col John Myers" Petie 3rd Dragon 1/32 scale The infamous Dragon P-51D in 1/32. This model was started before Tamiya announced their kit, and I have to admit that during this build I did consider scrapping it more than once. In the end, I am very glad I did not. Despite the challenges and limitations of this kit, I am very happy (and proud) of the end result.

Building the Mini Cooper S Countryman, a guide for beginners Hasegawa #24121 - 1/24 scale The aim of this article is to give the reader a detailed and comprehensive guide. Here you’ll have typical indications for the most experienced modelers but very useful for newcomers or for those about to take their first steps into scale model cars. In spite that this kit is simple, it’s very important to follow the instructions to avoid unexpected surprises. In spite that modelers use to skip or change the order in the instruction steps, I’ll build this kit as per instructions.

Building an improving the Protar Mclaren MP 4/2C - 1/12 scale ( revised with new pictures) My objective when I built the PM4/2 was to have a depiction of that car, with the quality aspect of Tamiya's McLaren MP4/6 kit, due to the similarity of both cars, and the building materials. The purpose of this note would not be to tell you how I built the model, because this kit has been discontinued more than ten years ago, so it is quite difficult to get one. I don't think it is reasonable to write a thorough note on specific details; so I will concentrate in general detailing that can be applied to other models with similar characteristics... and quality.

Tamiya Caterhams, a step by step guide for novices 1/12 scale The first Catherham from Tamiya coming to my hands at the end of 1994, was the “Cycle Fender Special” (10202), since the “Super Seven BDR was out of stock, and it was impossible for me to get it from the stores I used to buy kits. From that moment on, my affair with which, I think is the best scale car kit ever produced, began. And here my comment: probably, you have seen better detailed kits, or even superb models limited editions.

Tamiya Porsche 911, A weekend project for novices 1/24 scale This Porsche 911 has been built in a few nights to be entered at the “Trofeo Tamiya” which took place the day I completed the model. I normally have no problems in starting new projects but then I struggle to finish one, except if I have to enter a contest. At that time the 911 Carrera was a relatively new issued kit, so mine would have been the first one seen at a contest in my area, that’s the reason why I choose a non-standard eye-catching color and showy wheels.

Building rusted cars - VW 1966 - 1/24 scale It all started with a joke, I built a rusted Mustang GT 350 to make a gift to a friend who only builds Mustangs. It was at a modelers meeting when he received a homage and the joke consisted of letting him know the arduous remodeling and restoration work he would have with this rusted Mustang. I took advantage of my work and presented it in a contest that took place in Campinas city. Finally, the model was “best of the show” and they called me mad for giving a winning model. My answer was.... I will have to make another rusted model for me.

How to build a winner. Ferrari F2001B (First place TamCon 2005) 1/20 scale Here William offers us a large article, step by step, with pictures during the whole building and a commentary about what we are looking, he calls this a diary, but I think that’s the state of the art of the patience to take pictures. Thanks for the time and effort William spent on writing this article for Modeler Site.

Building the Tamiya Ferrari 310B first place TamCon 2003 Tamiya 1/20 scale F310B was a 1997 Ferrari F1 contender. It was very close to take away world championship from Jacque Villeneuve that year until the final nasty collision caused by Michael Schumacher. As a result, Schumacher was the one got thrown off the track and Villeneuve went on the win the driver championship. Later Schumacher was disqualified that year too. Very memorable year especially when Schumacher was fighting all points back and it made thing exciting.

A cutaway Testarossa Tamiya 1/24 Usually I am not concerned with production cars but, inspirated by some drawings published in Quattroruote (the most important Italian cars magazine) during the 80’s, I decided to start a series of cutaway models, revealing the beautiful technique hidden under their body panels. Some sport cars from the Tamiya range (namely Ferrari) are the perfect bases to carry out this long-term project, so let’s begin with the Testarossa.
