Hello all, These are my new Junghans Vienna style puzzle pieces. It seems it fell of the wall some years ago and was never put back together. I plan to attempt to and have just purchased some hide glue as I read on here was the thing to use. Is there a reliable way to date this one? Is it possibly 100 years old or did Junghans build these in the 1970's or so? The case looks newer than my others and the two surviving side glass pieces are held in with metal push clips. The pendulum feels hollow with no real weight to it. Any advise on reassembling? Some of the small missing veneer pieces will show when together but that is a skill I don't possess. Thank you for any thoughts or ideas.
