The traditional model builders follow the special appreciation of Swedish WIKING collectors with a gas transport semi-trailer with the tractor of the impressive Volvo N12. Koppartrans was once a Swedish fuel brand founded after the war in Gothenburg. Like ASG, Koppartrans was one of the most famous brands on Sweden's roads in the 1950s and 1960s. Koppartrans was created in 1953 from the merger of Stora Kopparberg AB, which is considered one of the oldest companies in the world, and Trans-Atlantic, a subsidiary of Ahlmarks. In 1964 the fuel company was taken over by Shell, but even a decade later the name Koppartrans was occasionally seen at petrol stations before it disappeared from the road picture.Tractor with zinc-yellow door access, interior fittings with black steering wheel.
