Movin On Estate Sales

This early clock came from the same great local estate most of these antiques came from. I couldn’t find a name on it but researched the hallmark on the face. That brought up the same hallmark used by Union clock Company Furtwangen Germany. I don’t know a thing about it so please look at pics carefully. It is complete. Two keys. The one on right is for the alarm/bell and works. I think the left key is to wind it but didn’t want to wind too tight and break. But I believe it is wound too tight…Unless I’m doing something wrong. Also, there is writing on inside of the door (seen in pic) which I can’t make out.
