This trick works for cameras with an override for the double
exposure prevention but many cameras do not have that so you are
stuck with losing a frame.
The highest speed on most shutters is wishful thinking
anyway. The time is measured for the half way open points for the
full aperture of the shutter. When stopped down the effective
exposure can be considerably longer. Since B&W film has a very
large overexposure latitude one can probably shoot at the next
slowest shutter speed and still get a good negative.
Both Compur and Kodak shutters can be forced into the highest
speed but it doesn't do the shutter any good.

Hi Jan:
My Rolleiflex 2,8C and Rolleicord IV and Voss Diax IIa, the three cameras from about 1954 have the same curiosity for the Compur 0 and 00 and 000 size shutters to set 1/500th sec shutter speed due to a second spring as Richard explained. I "discovered" a trick to set 1/500 after you cocked the shutter for these cameras: I attach the lens cap to the lenses and release the shutter, I set 1/500 and I cock the shutter again using the double exposure mechanism; I don't use this way often BTWm but it works fine..-
