Serial Number 307884 was reported as inaccurate.

Note: Hello, My movement on serial #: 307884 is all
nickel with the alternating wave type patterning.
So far, this is the only difference, though it
was sold as a 17 jewel, Im finding more
information to confirm 7 jewel....still looking.
Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
