The Tatra factory in the Czech Republic has for a long time been building heavy cross-country vehicles. The Tatra 813 8 x 8 heavy truck has been built since the late 1960's. It was used by various Warsaw Pact armies and also served for many civilian purposes. With its excellent cross-country mobility, it is also a favourite at truck trials.
Wikipedia has more information about the original.
A
version with a dozer blade and canvas roof is also available.
The model is simply a scaled-up version of my
6 mm scale model. Some parts have been made thinner, but no extra detail has been added.
