Not exactly a direct contribution to this thread, but I recently came upon what has been thought to be an early dipping system. Not moving the headlight beam, but reducing the light emitted. Anyone with film or theatrehistory might well recognise something similar for a lighting desk, similar but very much bigger for mains. This is probably for 6 or 12 volt, badged Jos. Lucas Limited-Patented-Birmingham. Perhaps inaccurate identification will be challenged within half an hour. I think it would be highly unconvincing mounted on the dask of even a Chummy as dubious as mine, so would be very happy to pass it on to someone who has been looking for one for years.
How does one reduce the size of the image on the post?
