Shutters anno 1937

Noch eine andere Seite aus meinem Photo Porst Katalog von 1937. Diese hier ist über die bei Porst damals verfügbaren Zentralverschlüsse. Die berühmten Marken waren Prontor (hergestellt durch Alfred Gauthier in Calmbach) und Compur (Friedich Deckel in München). Interessanterweise waren bei Konkurrenten später Teil von bzw. kontrolliert durch die Carl Zeiss Stiftung.
Die gebräuchlichste Kameraform der 1930er war die Faltbalgenkamera für Rollfilm. Das Meiste der  Mechanik nebem dem Filmvorschub war rund um das Objektiv gruppiert und das war Verschluss und Blende. Schaut man in den Katalog, so sieht man, dass fast alle Kameras in unterschiedlichen Verschluss- und Objektivkonfigurationen angeboten wurden. Es ist nicht selten das damit die Preise bis zu Faktor 4 variieren können, für's selbe Gehäuse! 

Yet another page from my Photo Porst catalog form 1937, this one is about the available leaf shutters at the time. The most prominent brands were the Prontor (manufactured by Alfred Gauthier in Calmbach) and the Compur shutters (Friedrich Deckel in Munich). Interestingly both somehow competing companies were part of or controlled by the Carl Zeiss foundation.   The most common camera design of the 1930'ies was the folding camera for roll film and most of the mechanics of the camera beside film forwarding were located around the lens being the shutter and aperture. Looking into the catalog you can see many cameras have been sold in many different configurations as combinations of the different leave shutters mentioned on this page and different quality standard lenses. With that the price can vary by a factor 4 for the same camera body.     

Here is a the translation of the text in the picture, for anybody interested...

For all cameras at Photo-Porst only original shutters are used. The much cheaper replacement shutters are generally not sold. For the few Marks that can be saved the excellent execution of the original shutters is better. On an original shutter, there are almost no repairs. The question of selecting a shutter is purely a question of price. Simple shutters are so cheap, because beside  from the two settings for time exposure they only have three different speeds and are easier to build than the Compur shutter offering 10 to 11 different settings.
