   There should be a pin inside the cable release socket.
They are often missing. If its not there the end of the
cable release will hit some levers inside the shutter
causing it to jam. Fixing the jam is easy but the problem
will happen again if the pin is not replaced. I don't know
the size, its possible a bit of drill stock would fit. The
length is not too critical.

best expert on Ilex shutters.
