Hi Karolina,

I'm not sure if you saw my previous inquiry but to move this appraisal forward, I'm appraising it provisionally based on the information provided. If you are able to answer my questions, I'd be delighted to evaluate it more specifically.

Information about E. Petitpierre, a barometer maker in Berlin, is quite limited. However, historical references suggest that a barometer associated with the name Petitpierre was notable in Berlin during the 19th century. In a scholarly article discussing time discipline in early modern Berlin, it's mentioned that "the point Archimedes sought from which to move the earth lies for the Berliner between the Academy clock here and Petitpierre’s barometer over there," indicating that Petitpierre's barometer was a recognized landmark or instrument in the city

There is a record of barometers marked "R. Petitpierre Wiesbaden" being sold at auction, which may suggest a connection or family relation, although this is speculative.

Based on the photos and information provided, and subject to examination, this is:
