The ones I had installed in Germany( also Bavaria-Muennerstadt) didn't have any file work on the EL itself. Granted, the notch in the extractor was filed in. My friend had a device that looked like the backend of an EL, except that instead of the headspacing screw, there was a hole, into which the pilot of a "spot facer" fit. The spot facer cut a section of the rim recess flat, to fit the headspacing screw. If you have one that has had the headspacing screw filed ( instead of flattening the rim recess), you should be able to turn it a little bit and refit it.
