Serial number date vs. ship date · measured from the factory letters
How long did Winchester take to ship a gun?
Across 180 factory-lettered Winchester guns whose record shows both days, half shipped within 45 days of the day the factory applied their serial number — the other half took longer. 8% shipped within a week; 13% took more than a year. Set aside the quickest tenth and the slowest tenth, and every gun left shipped somewhere between 9 days and about 14 months after numbering.
Model by model

| Model 1873 | 32 | 68 | 13% | 16% | 706 days |
| Model 1885 | 25 | 45 | 12% | 12% | over 3 years |
| Model 1892 | 14 | 42 | 0% | 7% | 381 days |

The lettered guns behind these figures — guns with a factory letter from the Cody Firearms Museum, the per-gun record described below — were numbered 1882–1912. Models with fewer than ten lettered guns showing both dates are left out of this table and counted only in the all-models figures above. Longest wait runs from numbering to the earliest recorded shipment; waits past two years are shown as “over N years.”
The three dates on a factory letter
A factory letter from the Cody Firearms Museum gives up to three dates for a Winchester of this era. The wait measured on this page runs from the first to the last.
- Serial number applied. The day the receiver was numbered. Collectors call it the Polishing Room date, or PR date; the museum calls it the serial number application date. It is the day the serial-number tables record, and the day the law treats as the gun’s date of manufacture.
- Received in warehouse. The day the finished gun was logged in, ready for sale.
- Shipped from warehouse. The day it left the factory on an order. Where a letter shows more than one shipment, the first is the one counted here.

Why the wait?
Applying the serial number was a step in the middle of making a Winchester, not the last one. The receiver was numbered, then barreled, stocked, and inspected — and the finished gun went into the warehouse to wait for an order that wanted its caliber and barrel length. Guns left in batches for wholesalers and dealers, and special-order features could hold a gun for months. The longest recorded wait in the letters is 2,665 days — over 7 years. (Guns that later came back for repair and shipped a second time are counted by their first shipment only, so a return never inflates a wait.)
The rule of thumb collectors pass around is two to four weeks from numbering to the warehouse, then a day to a week more to ship. The letters bear that out for the quickest guns and not for the rest: half waited longer than 45 days, and 13% waited more than a year.
What this means for dating a gun
The serial-number tables on this site — and the factory’s own application ledgers behind them — date the day a gun was numbered. They do not date the day it shipped. For most guns the two are weeks apart. But the year a gun shipped can differ from the year a serial table gives, and for questions that turn on the exact date — the pre-1899 antique line most famously (US federal law treats guns made before 1899 as antiques) — that difference can matter. The Model 1894 page works through that case.
This is also why nothing on this site dates a serial from a shipping date. The records behind these figures are item-level factory events, kept out of serial dating on purpose; measured together, they describe the factory’s rhythm. Date a gun by its number, then reach for the letter when the exact day matters. About the records →
Questions
How long did Winchester take to ship a gun after its serial number was applied?
Half of the 180 factory-lettered guns measured here shipped within 45 days of numbering. 8% shipped within a week; 13% took more than a year. Setting aside the quickest tenth and the slowest tenth, the rest shipped between 9 days and about 14 months after numbering.
What do the three dates on a Winchester factory letter mean?
Serial number applied is the day the receiver was numbered, also called the Polishing Room or PR date and the serial number application date; it is the day the serial-number tables record and the one the law treats as the date of manufacture. Received in warehouse is the day the finished gun was logged in, ready for sale. Shipped from warehouse is the day it left the factory on an order.
Is a Winchester's date of manufacture the day it shipped?
No. The date of manufacture is the day the serial number was applied, and shipping came later: weeks for most guns, more than a year for 13% of the lettered guns measured here. For the pre-1899 antique question — US federal law treats guns made before 1899 as antiques — it is the serial-application date that counts, and a factory letter is the way to confirm it.
Does a Winchester factory letter show the shipping date?
Usually, yes. For the models on this page a Cody Firearms Museum letter typically records the day the serial number was applied, the day the gun was received in the warehouse, and the day it shipped, along with what the ledger noted about the gun.
How this was measured
The guns counted here have Cody Firearms Museum records — factory letters, and for 24% of them the museum’s search printouts of the same ledgers — that were published in auction catalogs, with the day the serial was applied and the day the gun shipped both readable in the record. In more detail:
- Every date was transcribed from the page image in two independent review passes, and only dates both passes agreed on are used. Approximate or year-only dates are not counted.
- One gun counts once. A gun lettered twice, or a letter scanned twice, is one record; a gun whose records give two different numbering dates is left out.
- Where a record shows more than one shipment, the first is the one counted. Return and repair shipments never enter the figures.
- 4 records where shipping appears to precede numbering, or to run more than ten years after it, are left out as ledger quirks — a transposed year in the ledger or in the reading of it.
- As a check that each pair is really one gun: 179 of the 180 records also show the day the finished gun reached the warehouse, and every one of them reads in order — numbered, then received, then shipped.
- The figures are the median and simple shares, not averages: a few very long waits would drag an average up without describing the typical gun.
Lettered guns are not a random sample — people letter guns that are unusual, valuable, or already documented — so treat these figures as the shape of the factory’s wait, not a promise for any particular gun. Serials, letters, and provenance stay out of these pages by design: what is published here is the measurement, never the gun.
