Up for sale is a Antique Telegrapher's Galvanomter ammeter.  I can't translate the writing.  I don't have a way to test to know if this works.  

If you have any questions please ask.  I will do my best to answer them.  Please see the photos to know exactly what you are bidding on.  I am selling my father's military collection, so if that is your thing please see my other auctions.  

I am not an expert and I do my best to identify each item. 

I will combine shipping on items bought on the same day.
