In 1950 the former mechanic Václav Uhlík from
Líně in the
Czech Republic found the wreck of an RR-7 artillery tractor. He repaired and rebuilt the machine as an armoured carrier. On 25 July 1953, with seven passengers in the vehicle, he got through three border zones including wire obstacles, and penetrated thirty kilometres into
West German territory. There he applied for asylum and emigrated to the
United States, where the machine was exhibited as the "freedom tank" (Czech:
tank svobody). It is now owned by a private collector. ==References==
