perhaps my favourite camera is also my oldest one, a voigtländer E-messer from the 1930ies. It is a 6x9 camera with a compur rapid shutter. Now, the slow shutter speeds are way too slow. 1/10 is more like a full second, and 1 second is like 10. The faster ones appear to be allright. Some movement within the shutter is simply not fast enough. I wonder, is there anything I can do about it? It would be great to use this camera over the weekend.

Thanks in ahead all of you, and happy midsummer, which is an important holiday in my country.
