Colt 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.
Colt is the exception that proves the rule: the records survive and the company still reads them. The archive is run as its own operation, the letters arrive on embossed stationery with the signature of the Colt Historian, and the collector market treats them as the definitive document for a Colt. That authority has a price and a wait, and both have moved in one direction. Collectors reported a Colt letter at $65; the published list now runs $80 for many revolvers and pistols, $105 for the higher tier that includes the Single Action Army, Python and New Service, and $205 to $305 for percussion models. Turnaround is quoted at roughly 150 days. Expedited service exists and costs a further $100 — or $150 on a First Generation Single Action Army.
Can a serial number date a Colt?
Yes — the maker publishes a table, so a year can be estimated from the serial number against a source you can check yourself. The date is only as precise as the gap between two published entries, and manufacturers do not build in strict serial order.
