Claude, those are Piper window winders and are different to the later 411/412 systems. My 410 also has factory fitted electric windows like these. They are fast and powerful, but the microswitches can be unreliable when their cast alloy bodies tend to crumble and fail. One of yours is missing the microswitches which may be why the mechanisms were swapped for the US ones. The manual winder has been very useful to me - not to wind it all the way up but just a few mm is enough to then have it work electrically.
