Serial Number 3598843 was reported as inaccurate.

Note: The movement for this serial number is different
than the pictured model 6. My watch, serial
#3598843 is a model 7 "Stewart Special" exactly
as your page for Illinois 606 #2883884. I can send
a picture if that would help.
Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
