Before World War II, the Danish company Birk produced diecast models based on products made in the USA by Tootsietoy. In the 1950s and 1960s, several Danish companies produced diecast and plastic scale model cars in large series. Apart from its construction kits, the Lego toy company also released 1/87th scale model cars from 1955 to 1968. The plastic models of cars and trucks featured windows and steel wheels and axles. Similar models had been introduced by a company called Pilot in the 1950s. Lego also made a few plastic models in larger scales (1/38th and 1/43rd scale). At the same time, Tekno produced detailed 1/43rd (cars) and 1/50th (trucks) scale models. The costly type of construction was one of the reasons why Tekno had to close down in 1972. Before that, the models had been marketed under the name of Kirk for a short time. The Dutchman John van Min acquired the right to use the brand name and started a range of Tekno truck models in the Netherlands in 1974. Another Danish manufacturer of diecast models was Vilmer, producing car and truck models in 1/43rd to 1/50th scale from 1952 to 1971. Especially in the 1950s and 1960s, there were even some more Danish companies producing toy or model cars made of metal or plastic, e.g. BP, Blue Sun, LKE, HP Plast, Tobitoys and Wittrock. A more recent Danish manufacturer, EpokeModeller, was established in 2001 and has specialized into 1/87th scale resin handbuilt models of commercial vehicles and model railroad accessories. The Danish super sports car Zenvo ST1 has been released by FrontiArt as a detailed 1/18th resin miniature and by MSZ as an inexpensive 1/32nd scale diecast model.
