Hi, here is a picture of Junghans Diana Mystery clock. I have one of those statue (f.iffland signed) but with the jewel bar screwed instead blocked with th screw on the top like this one The difference i found is on the jewel bar that is fixed in different way. This one has a screw that fixes the bar in the right arm, the other one has a jewel bar screwed inside the arm. Any considerations about it? The jewel bar in this photo seems to be different from mine.
