Trona
The Trona is a folding plate camera, originally made by Krugener. Manufacture was then continued after the creation of Ica, and was one of Ica's models produced after the merger which formed Zeiss Ikon. It was available in two plate sizes, 9x12cm, 6.5x9cm, and was supplied with different lens/shutter combinations. The camera has double extension bellows with front rise and cross movements.
