I have seen the great German movie The Lives of Others a few years ago which gave an important role to a Kolibri portable typewriter in the story. One of my old dreams came true when I recently found and purchased a beautiful black Groma Kolibri.
Kolibri on the Netherlandish Schrijfmachinist site is made in 1959 with the serial number 632 950 which is definetly larger than mine. There's no guarantee I'm correct of course: very little information is available on this.
Did I show a closeup of the logo on the cover? No? How could I not have inserted this picture right at the beginning of this post?
