Rare moss-green typewriter Kolibri Groma from the 1950s. This typewriter from East Germany was far ahead of its time. Quantity and robustness were more important than quality and elegance in the GDR. But there were some exceptions, like this type: an ultra thin, ultra chic, ultra capable typewriter. De Groma Kolibri. A gem in an otherwise dull landscape. The brand name Groma stems from combining the original company name Maschinenfabrik GFGrosser. This machine is numbered (see photo), it has traces of wear and 1 half rotary knob. Will be professionally packaged and sent by registered mail.
