(As you slide up the rewind knob, the gears are engaged - done this way so the rewind knob doesn't spin when winding film. The add on device allowed no tolerance so that the rewind knob could be turned ever so slightly when raising to engage rewind gear - like when pulling a manual transmittion car into first gear and the gears don't mesh.) For awhile I carried small screwdriver to remove the add on rewind crank if the jam, described above, occured. Let me know if you have a newer version that that gives some fiddle room on the rewind knob. Jim James H.
