Construction / Eitech - Construction Sets
A range of metal construction sets that used to be sold under the 'Construction' name, but now sold under the 'Eitech' brand name. It is a metric system with 10mm hole spacings and 4mm thread and was originally manufactured in the GDR. Following German unification the company's name changed to Eitech GmbH. This changed again a few years later to Eichsfelder Technology eitech GmbH. The company's website is https://www.eitech.de/. See 'Construction (East Germany)' for manuals etc. of sets made prior to the unification of Germany.
