Iver Johnson factory records
Who holds this maker's production records today, whether a serial table exists at all, and what it costs to have the archive read them.
Iver Johnson is a maker whose output was enormous and whose records were not. No serial table is published, no letter service operates, and the company has changed hands repeatedly since the original firm closed. Dating an Iver Johnson means working from the model, the markings and the collector literature — and accepting that the number alone will not do it.

Can a serial number date a Iver Johnson?
From the serial number alone, generally no — and that is the honest answer rather than a gap in this site. There is no published table to compare the number against, so any year you find online for this maker comes from a secondary reconstruction, and those are exactly as reliable as their author.
Dating then rests on what is on the gun: the maker's marking and address, the model and its catalogued period, proof marks and their era, patent dates, and the manufacturer's own model history.
