Serial Number 4492341 was reported as inaccurate.

Note: I have not uploaded pics yet, but the movement
says "Bunn Special" and does not have any
indication of a 60 hr barrel. I have fully wound
it and let it run down and it is definitely a 40
hr barrel.
Curator Response: Thanks for the report. There are other reports of Model 11 movements (48-Hour) in this run. When you have a moment, please upload images for further evaluation and documentation. Thanks!
