During the WWI, the Germans produced their SDKFZ 251 in Pilsen. The production was taken over by the Czechoslovakian communist regime. New-born vehilces were equipped with Praga, and later Tatra engines. Everything in the vehicle is manual, giving things little chance to break. Spares, except for body parts, are difficult to find. Front tyres are all-rubber, so there is little need to change them. Although the very concept of a half-track makes relatively little sense, the experience of driving one is stunning. Besides, there is plenty of space in the driver's compartment. We stronly discourage you from turning any of your OT-810 into a worthless SDKFZ copy.
