Anonymous · September 27, 2021

Serial Number 676504 was reported as inaccurate.

Note: This movement, as shown on ebay, is NOT MARKED
SPECIAL (all my Specials have that
identification), nor does it have the frequent
2-tone overlay or the alternate nickel with gold
screws and a gold micrometer. I'd think this one
may have been an anomaly in a mixed run.
Curator Response: I agree. I have moved this information to the research notes for the run so it is less confusing.

Note: Gold or gold washed movement, or perhaps called 2
tone. Whole movement is gold colored but has
nickeled micrometer, screws, etc. to contrast.
Also, movement is marked SPECIAL.
