These small portable, or Ultraportable, phonographs have been called by various generic names, including Camera, Box, Pocket and Trench. It is obvious where the first three names come from, but Trench is probably not quite so obvious. They were often used by soldiers in the trenches, hence the name.
The Colibri was made in Belgium.
Some had a totally different sound box where the diaphragm was "hidden" by a ridged cover. Presumably to protect the diaphragm.
They close up very small, but surprisingly weighty!
