MERLIN  (by United Optical Instruments), UK  c1936
All metal submini camera using 16mm film. It is a very basic-simple camera: one speed, fixed focus - just press the trigger and turn the film-knob on to the next pic. no identification, nor any other text, serial etc on the camera. yet, I do find it interesting in design.
* Also, colored Merlin-cameras were made in green and blue.
