Perfect; just what I need, and thanks. How, by the way, mechanically, does the battery-operated winder know that the exposures are exhausted. It does some how because the winder runs until manually shut down once the there film is used up, but stops appropriately until then. Must have something to do with the perforations, but I can't quite figure out the mechanics of it. (I'd test with a manual advance but the camera I have doesn't work on manual advance). Thanks again.
