This drop-plate 9 x 12 cm box camera was manufactured by ICA AG. of Dresden, Germany in the 1920s. The small plaque on the back of the camera shows that it was imported for sale in Russia by V. Metenkov of Ekaterinburg. As Ekaterinburg had its named changed to Sverdlovsk in 1924, it was almost certainly imported before that date.
