Here we have a Antique Westinghouse Type SM A.C. Ammeter. The meter is quite large measuring 7 3/8 inches across and 4 inches deep not including the length of the bolts on the back. It is in good condition with undamaged glass and no dents or other damage and just needs a little cleaning. The dial face reads Westinghouse electric and manufacturing co. Pittsburgh, PA. Type SM A.C. Ammeter style 156625B 45-65 cycles. The latest date on it is a patent date of July 11, 05 meaning 1905. This is a neat piece that would make a great addition to your collection. 9-10 pounds
