Agfa Isolette

The Agfa Isolette (printed Jsolette on the camera, because the capital letter "I" was often printed as "J" in Germany) was made from 1937-42, then later from 1946-50. I'm not sure of the date of this one, but I think it might be from 1937.  Apparently they were known as "Soldatenkamera" (Soldiers' Camera) during WWII. 
 
It takes 6 x 6 negatives (12 on 120) but could have been adapted to take 4.5 x 6, 16 on 120; the Apotar lens (f = 8.5 cm) focuses from 1 metre to infinity; the shutter has 1 sec to 1/300 sec, and B and T; apertures are from f/4.5 to f/32.
