We do not publish charts for that make yet

This is a refusal, and it is deliberate. The lookup only uses production charts that the manufacturer publishes itself, in a form that can be read and cited. Most makers do not publish one — and for those, no honest tool can give you a year.

Date your firearm by its serial number

Every result names the documented threshold it came from, so you can check the reasoning yourself.

Open the serial number lookup

The rule that decides coverage

A make is covered here only when the manufacturer publishes its own serial or date chart as a browsable table on its own support pages. That is the whole test, and it is strict. Everything else is declined, including some very large makers:

What we will not do. We will not guess a year from a surname match, from a model that looks similar, or from a number that happens to sit in a plausible range. Every result on this site names the documented threshold it came from. Where there is no threshold, there is no result.

Makes we do cover

Coverage grows one transcription at a time, and only when a maker's own published table can be read and cited:

That list is short, and it will stay short. Browsable official charts are genuinely rare — which is exactly why a tool that states its sources and its limits is worth more in this subject than one that answers everything.

Where to go for a make we cannot cover

Our maker guides cover the history and the records situation of individual brands, including which of them still issue factory letters and where their archives are held.

Can I request that a make be added?

If the maker publishes its own chart as a browsable table, coverage follows automatically once it is transcribed — that is how the existing makes were added. If they do not publish one, no amount of requesting creates data, and we would rather tell you that than invent a year.

Could you use a third-party lookup service to cover more makers?

Technically yes, and we deliberately do not. It would mean depending on someone else's endpoint, publishing a result we cannot show the source for, and losing the property that makes this tool worth using at all: every answer traceable to a document.

Is a wider database of gun serial numbers available anywhere?

Not publicly. Stolen-firearm records sit in law-enforcement systems that only law enforcement can query, and manufacturer archives are private. No public service takes a serial number and returns an owner or a history. What is public is the production chart — narrow, and the only honest basis for dating a gun.
