Most of the folding cameras of the mid-1920's were of vertical design. The Toska was an exception. It is of vertical design, otherwise of conventional design. It was available in 10 x 15cm and 13 x 18cm sizes, with Helka, Litonar, Tessar or Doppel Protar in Automat XI or Compur dial set shutters.
The Toska was of Contessa Nettel design, and when they became part of Zeiss Ikon in 1926, it was not carried over into Zeiss production. The remaining inventory was given Zeiss markings and sold off. The camera was not listed after 1927.
