The only Scandinavian company to become an accomplished diecast metal toy producer, Tekno was similar to the German Schuco Modell, Marklin, or Gama Toys, which, like Tekno, were all model firms existing pre-World War II. The founder was A. Siegumfeldt, a plumber from Copenhagen, who, after many years of producing wooden toys, began producing diecast vehicles post-war in 1945. Through the 1950s, Tekno gradually became a main competitor even to diecast powerhouses like Dinky (Rixon 2005, p. 34).
Brochures show that the company regally celebrated its 25th anniversary in 1953. By this time a wide variety of trucks, tractors and cars were being produced along with toy miniature pots, pans and other kitchenware (Tekno Dansk 1953). Wooden houses, cranes, trucks and other toys - even small electric motors - were also made, sometimes in association with the Swedish company Brio, were also produced in the 1950s.
Tekno diecast cars and airplanes were manufactured previous to the war, however, from 1949 through about 1969, many Tekno models were made by H. Langes Legetøj (Langes Toys), a diecaster in Copenhagen with which Tekno had a gentlemen's agreement (Rixon 2005, p. 35).
Langes Legetøj also cooperated with a company called Termax - in the same building. Termax developed many of the model cars, for example, all Mercedes models, Jaguar E type, Opel models, and the DKW Junior. They then were often produced or assembled by Lange's Legetøj..
Some of Tekno´s parts were cast in Nyrnbergade (Langes & Termax) then sent west about four miles to Kirkebjerg. Tekno even had a larger factory on Rentemestervej and one also in Frederikssund. Later, production was also done in Glostrup about three miles west of Kirkebjerg. Langes Toys were bought by Kirk toys in 1958 which replaced the Tekno name with Kirk on some vehicle bases. In 1969, the old agreement between Langes Legetøj and Tekno was terminated. Kirk had existed as early as 1892 as Emil Møller Phone Factory. Since 1970 the company has been traded many times. For some time it was Kirk telecom and then in 2012 became Spectralink Europe ApS. Kirk is a family name, and in the period 1923-1967 the family stood at directorship of the phone factory. Apparently, Kirk's involvement in the toy business was a small venture compared to greater phone production.
Tekno was known for favoring Swedish auto maker Volvo, making coupes, sedan, and wagons. Some of these models were used by Volvo as promotional models. Tekno had a reputation for accuracy and realism - its Volvo models and many others like its Oldsmobile Toronado and Jaguar X-KE had superb proportions and detail (Sinclair 1979, p. 391). Tekno trucks were also known for detail, such as the Ford D-800 tilt-cab decorated for Tuborg Beer which featured thirty-two removable beer cases (Sinclair 1979, p. 391). Still, in the early 1960s, the company often used the unrealistic, flashy practice of using jeweled headlights, similar to Dinky, Corgi, or Mebetoys (Gardiner and O'Neill 1996, p. 18).
An analysis of one particular Tekno, no. 928, the Mercedes-Benz 230 SL convertible in 1:43 scale, shows the company's attention to detail. The model's hood, trunk, and both doors opened. The engine compartment was very detailed. Wheels were produced in three parts: rubber tire, painted wheel rim, and metal cap with the Mercedes star. The wheel detail alone gave the car a feel of being realistic and solid. The front grille was slotted and one could seen inside to the 'radiator'. On this model, headlights are done in clear plastic, though rear lights are painted onto precisely shaped metal trim. The doors open and the windows are rolled UP, unusual for diecast models since, for such detail, extra parts are necessary, raising costs. In the interior, the dashboard and steering wheel have accurate shapes and the seats not only tilt, but slide back and forth. There is a spare tire in the trunk. The chassis is painted (usually white) whereas most 1:43 diecast manufacturers often left it bare. One manufacturing problem was that with the opening doors, the front and rear sections of the car's diecast body were only connected by very narrow strips of metal causing the body to droop downward at each end, causing the rear to sag away from the doors,so the doors don't fit finely to the body. In the hands of rough youngsters this model probably did not stay in one piece very long.
More than any other diecast maker, Tekno was known for its variety of liveries and their variations, which could seem nearly endless. For example, veteran collector Cecil Gibson wrote as early as 1970 how Tekno in the 1960s made its Volkswagen Transporter panel truck and Ford Taunus vans in many liveries, such as the Dutch Amstel Beer, and for Scandinavian products such as the Politiken newspaper, or the more well known Scania (Gibson 1970, pages 28–29). Tekno's Scania and Volvo trucks were also offered with a variety of advertising on their flanks. In fact, Tekno may have been the earliest diecast company to focus on promotional products, perhaps even earlier than Winross Models' diecast trucks out of Rochester, New York - known in the United States for having many promotional variations.
Teckno had already in 1935 agreements with Falck, concerning advertising of tinplate cars. A more commercial use of advertisements on toy cars started with the VW van in 1953
Tekno boxes were normally rather dull, usually being red with illustrations of the cars on the sides. Earlier boxes showed illustrations of cars in various street scenes. Some of the colors could be brighter, however, as with the chartreuse color used on boxes introducing "Fingertip Styring" (sic)(Gardiner and O'Neill 1996, p. 37). Oddly, a 'cut-off' hand appeared apparently out of the sky to touch and guide the car along. Through the 1960s, boxes became more simple as cars were portrayed with apertures closed - and then open on the opposite side (Rixon 2005, p. 35). The red box flaps showed the car in a yellow or white band across the center of the flap, or boxes were red on one side and blue on the other (Gardiner and O'Neill 1996 pp 36–37). Later, and like the rest of the industry, plastic window boxes with white and red trim became commonplace - obviously putting some talented graphic artists out of work (Ilich 1995-2000).
Normally producing in 1:43 scale, Tekno's principal rivals were Corgi and Dinky - formidable competition. Models produced often mimicked their offerings, like the Commer estate or the later Oldsmobile Toronado, both models made by Corgi. Still, Tekno always had a personality all its own, offering unique vehicles (particularly those Swedish Saabs and Volvos). One example was the 1970 Volvo 144 police sedan or the Saab 99. Another was the Corvair Monza concept vehicle, produced in several colors - later reproduced by Auto Pilen of Spain. Some Tekno original tooling for 1960s Tekno models was also sold to Dalia of Spain, like several Volvo, Ford, and Lincoln models.
In contrast with most other diecast car producers, Tekno did not give in to the temptation of low friction, flashy wheels on their vehicles. Though the company remained loyal to its roots in producing more realistic models, this was not good for sales. Gradually, the variety of cars and other vehicles gave way to marketing only diecast trucks - often still for promotional purposes. At least this strategy helped the company survive, though more in the mode of German Conrad or NZG.
Some earlier models suffered occasionally from zinc pest and warping or bending chassis (perhaps from moldings that were unreinforced), but, overall, Tekno vehicles were of high quality finish.
Some Tekno cars were marketed in the United States by Kayeff, Inc. of Arcadia, California in blister packages. Unlike Lonestar Toys sold in the U.S. by Physio-Chem, which did not advertise the Lonestar name on packaging, the Kayeff cars proudly displayed the Tekno logo on the blister and stated boldly "It's from Denmark!" with the Danish flag and crown prominently shown (Hobby Talk 2008). The cars were more likely to be colored in more "spectra-flame"-type colors, perhaps in an attempt to compete with Mattel's Hot Wheels. A few years ago, one of these was reported to have sold for $800.00.
MPC also marketed some Tekno trucks and cars as MPC. These were castings made by Kirk (Hobby Talk 2008). They were advertised as "Strip 'n Steer Metal Precision Trucks" as they could be taken apart and re-assembled.
Sometime in the late 1960s, Tekno models were also offered through a special mail order ad by Road and Track magazine (Hobby Talk 2008).
Sinclair says Tekno ceased making toys in 1972 (Sinclair 1979, p. 391). In 1974, Tekno tooling was sold to a Dutch firm called Vanmin, BV. Thus Tekno, now with the name "Tekno Toys" continues as a firm in the Netherlands. It is still in business, mainly making truck models with a variety of promotional liveries (Hobby Talk 2008). In 1989, due to the promotional and adult collector focus of Teknos offerings, the word "Toys" was dropped from the name (Tekno website).
