Serial Number 10421999 was reported as inaccurate.

Note: Maybe, it is not marked G. M. Wheeler. All other
data seems correct. Would be 1st from last 148
Grade made.

Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
