Note: Run 5,568,001-5,570,000 = 1942 So This # 5,568,495
= 1942 year of Production

From MICHAEL CHAMELIN "The 16 Size Illinois Bunn
Special 1913~1948"
Curator Response: Thanks for the report. It should be noted that the dates Chamelin published are estimates by extrapolation and even the author states that production during WWII may have ceased entirely. The database has been updated to align closer to these dates but still should be considered general estimates and not exact production years.
