Note: My Movement is clearly marked 8 Adjustments.
But Someone must have saw the ( __9_)
__Adjustments on their movement upside down and
changed it to 6 Adjustments. I have only seen 8
or 9 Adjustments on 571 Elgin Movements in the
last 10 years of Collecting .
Respectfully yours, Jerome Schley Sr.

Curator Response: 8 Adjustments = 6 Positions, 1 Isochronism, 1 Temperature.
