Serial Number 528551 was reported as inaccurate.

Note: All is correct but on mine, the Movement Markings
also has "5 Positions" added under Adjusted.
Apparently that change was made sometime in this
run because I have serial #524262 from one year
prior which only says Adjusted but is also from
the same run according to my Illinois
Identification and Price Guide by Roy Ehrhardt.

items gilded.

Curator Response: Thanks for the report. The private label listing includes labels that have been found in the run. These were typically produced in small batches, and the entire run is not expected to be marked with the same private label.
