While looking for various japanese style plastic robot kits I came across this model of a proposed secret German tank from WW2. I thought it had some good potential so took a chance on it.

As you can see the model came fairly complete with just one sprue containing the ariel mast and extra gun turrets. Should also say the model comes pre-painted in a fairly simple but effective scheme. The model is 45mm long, 20mm wide and 32mm high (including mast).

The underside of the model showing the four tracks in detail.

Here is the model after I had put all of the guns on it. You get a few spare guns in case you want a different configuration on the tank. But to be honest the guns only really fit in the configuration shown.

The detail on the model is very good, you can see in the picture various ladders, stairs, panels and even the rivets.

To help with the scale of the model it's shown here with an 2mm scale French Ironclad miniature from Brigade Models

and here with a 6mm infantryman also from Brigade Models.
Overall the model is very good and would work well for either Victorian Sci-Fi games or to repaint it as a 2mm-6mm Sci-Fi tank, but it is not currently in production and so availability is via places like Ebay and more often than not from suppliers in Japan.
