Since I am an artillery fan, this German heavy gun couldn’t miss in my collection not only due to its caliber and effectiveness but because once it’s built, it is 35cm long. Prepare the showcases!


As it always happens the way we use to mount artillery pieces is completely different to the way we’re accustomed when building military vehicles. The kit is complex and will need a lot of patience and peacefulness. It’s not a week-end project. As you’ll see along its assembly, the kit quality is not the best. We’ll have to be very careful and take things calmly.

Due to the letters on the sprues and there’s no doubt that Trumpeter thought to issue in the near future the brother of this K18 Matterhorn, that’s to say the 21cm version (21cm Mörser Mrs18 Brümmbar Ref #2314 from Trumpeter). I wish we could see soon in injection molded plastic, the older brother of the family, the princely and even bigger 21cm K38.

First inspection of the sprues shows quite a lot of visible ejector pin marks on parts, that perhaps during the assembly may remain hidden but at first sight are quite ugly and troublesome.

The plastic is more brittle than Trumpeter usually offer, this is why you should be very careful when cutting off the parts. They tend to crack leaving permanent marks.

This is a complex kit with lots of parts, some of them very small.


Step 1-2-3 – Gun carriage

In these steps I assembled the gun carriage This is the base the model will sit, so you’ll need to be very careful to get everything aligned and symmetric with all the parts straight.

The main parts come well detailed though in my kit due to a packing deficiency, a small distortion of parts took place Nevertheless, once assembled the whole straightens itself.
Assembly of these steps is not complicated but the parts have to be sanded and treated going over the edges and corners to assure a good fit of parts.

Besides, the instructions are a little confusing especially regarding the support structure of the base plate.
