In the early 1950s Atvidaberg commissioned Sigvard Bernadotte, a distinguished silversmith and industrial designer (and
a member of the Swedish royal family) to design new casings for the Facit machines and for the Original-Odhner 200- se
series.
The re-styled "New TK" was released as the Model NTK in 1954, with the sheet-metal covers being replaced with a
three-piece die-cast casing in two-tone green. The cover has no visible screws, but is held in place by two spring clips
concealed in the holes for the clearing levers. The octagonal keytops have been replaced by round for the numerals and
rectagular for the shift controls. The maker's details and serial number are on a large aluminium plate on the base of the
machine. The operation of the machine was unchanged, but there were a mumber of internal changes to refine the
details of the mechanism and to simplify the construction.
