Serial Number 954298 was reported as inaccurate.

Note: The 3/4 plate checkerboard 17J movements should be
series 9 for the 16s (Keystone) Howard's. There
wasn't any series 4 for the 16s.
Curator Response: Thanks for the report, but this is incorrect. Factory catalogs support the fact that there was indeed a 16-Size Series 4. https://pocketwatchdatabase.com/guide/company/e.-howard-watch-co.-keystone/catalogs
