Serial Number 428983 was reported as inaccurate.

Note: This is a two-toned movement, 17 jewels and is
marked as adjusted. DEFINATELY NOT a Grade 66.
Hairspring is on the right end of top
plate...Perhaps a Grade 61 or 62A.

Curator Response: Thanks for the report. I have added this to the research notes for the run.
