Iver Johnson Revolver Serial Number Database Best Link

Identifying the manufacture date of an Iver Johnson revolver is notoriously difficult because many official factory records no longer exist. However, by cross-referencing serial number prefixes, patent dates, and physical design changes, you can accurately narrow down your firearm's age.

If your Iver Johnson is a single-shot Champion shotgun, the dating method is different but even simpler. There is no need for a letter prefix. The format of the serial number itself tells you the decade of production. This system is widely accepted and originated with Bill Goforth.
