This camera is a Zeiss Ikon Nettel presscamera with filmsize 9x12 cm
and a tessar lens. It is the last version of the long line of
presscameras with deckrullo focalplane shutters. There are some
improvements between the Contessa-Nettel made Deckrullo I also have and
- Some wooden parts are replaced with steel
- Winding/shutterspeed setup is done with one knob instead of two knobs
in earlier models
- shutter mechanism is more simplified and a bit more reliable, but
more difficult to assemble
- the shutter curtain and strap/ribbon system is still the same and
still very difficult to repair
In this camera the shutter cloth was ok, but as usual the rubber
coating on the fabric was dried and ruined.
I disassembled the shutter and removed the old rubber with acetone. The
old rubber had twisted the fabric a bit , but with acetone and water I
could stretch it nearly to its old form. After drying, I secured the
brass parts attached to the cloth with some glue and then I
painted the cloth with Tulip Soft acrylic fabric paint. It took
several layers to make it entirely lightproof, but this paint does not
thicken or twist the fabric so the geometry and thickness stay the
same. Also the fabric remains as flexible as the rubber when new. After
cleaning the mechanism, I started adujsting the shutter speeds.
As usual in old focal plane shutters, they have never actually been
able to achieve the maximum speeds they are supposed to, so all other
speeds but the fastest are accurate enough by the standards of the time
when this camera was made. I have read several books and from other
sources from the early 1920's and 1930's which discuss the
functionality, usage and problems of focalplane shutters, that the top
speeds have actually been even in the best situations only half of
their supposed value. After all the work, I took some pictures with it
and despite of the unreliability problems with these kind of shutters,
it is still a very nice camera to use.
