ICA Dresden, Trix 311, Germany, 1915
ICA, or Internationale Camera Actiengesellschaft, was born in 1909 from the merger of four companies, Hüttig AG from Dresden, Kamerawerk Dr. Krügener from Francoforte, Emil Wünsche AG from Reick near Dresden and Carl Zeiss Jena–Palmos Camerabau from Jena; of the four, Hüttig AG was the oldest one. At first the company kept producing the most successful models of the four brands. In the fall of 1926 ICA Dresden was absorbed by Zeiss Ikon.
The Trix 311 was made from 1915 to 1920.
