No published table matches Winchester Pattern 14 serial numbers to years. Neither the surviving factory records nor the collector references provide one. What is known about its serial numbers is summarized in the notes on this page.
What to know about Pattern 14 serial numbers
- Each maker used its own serial number sequence with its own prefix: W for Winchester, R for Remington and E for Eddystone. The prefix is essential, so read it before you look a number up.
- The total made and the last serial number are not the same. 235,448 rifles were completed, but that does not mean the last serial was W235448. George Madis's tables report the numbered sequence passing 245,000.
- The Pattern 14 is the British .303 rifle. The U.S. .30-06 rifle that followed it is the Model 1917, and it started its own Winchester serial number sequence.
- The highest serial number is larger than the number of rifles accepted, because numbered parts that were rejected or replaced used up positions in the sequence.
