Hi!
Before ww2 british were importing a lot of presscameras, mainly medium sized upto 9x12 from germany and there seemed to be a lot of cooperation between German and British manufacturers at least with providing parts. Of course ww2 ended that and already slightly before, during and after the war British companies were using old stocked parts of German presscameras to make new British ones. Later brits started to copy american cameras and also there were few attempts to make newer versions of older German cameras. But it seems there were quite a lot of medium format cameras in use in uk and in europe in general already before ww2. I have noticed that in UK there was a big scene of refitting, repairing, combining etc... or what one would now call modding of old german cameras that lasted long way past the wartime.
On my website there are several typical examples of what was the idea of a presscamera in europe and also some unique British attempts in doing one based on the idea of the American presscamera.
