Note: W.M Ellery
Curator Response: Thanks for the report. Unfortunately, the images uploaded are not clear enough to verify the serial number. Additionally, the barrel bridge is a slightly different color than the rest of the movement, so it is possible that the bridge was swapped at some point. #439017 from this run has been verified as P.S. Bartlett, as the factory records suggest.
