I can only answer quickly that the EKT KG was dissolved in April 1972.Quote from the website ekt-modelle.de: 1972 April: Dissolution of the KG and incorporation into the VEB "Modell- und Plastespielwarenkombinat Annaberg-Buchholz" I will try to find out what happened to the VEB "Modell- und Plastespielwarenkombinat Annaberg-Buchholz" after 1989. I also do not know if the production of drive models was continued in this company (Kombinat).
