Private Mueseum Antique Alarm Clock

[ATI434]

I know this is a European made clock, three generations in my family, I know my family tried to find another one like this but was never successful to find one after fifty years of looking. Where can I find history and details about the technology and what is the appraisal.

Looks custom made to me, so I doubt that you'll ever find another one.
