To the maximum extent possible, the dates of manufacture shown were obtained from the original Winchester Factory Polishing Room serialization records; otherwise estimates were made using multiple sources of information (e.g. George Madis, Ned Schwing, etc.), in which case the data was extrapolated to the best of our ability. This information is no substitute for obtaining a Winchester Factory Letter from the Cody Firearms Museum (available for certain models and serial ranges) which in addition to the Serial Number Application Date, normally provide the original Received In Warehouse Date and Date Shipped from Winchester factory. For purposes of determining if your gun is legally considered an “antique” (pre-1899 DOM), the BATF has told us they use the DOM dates published by the manufacture (Winchester). Those dates coincide with the Madis dates and can be viewed on Winchester’s site at:Winchesterguns.com
If you would like to obtain factory research on your Winchester, we urge you to join WACA and the Cody Firearms Museum. WACA members who are also CFM Members will receive 15 additional record searches on top of the regular quantity of searches included in the standard CFM membership package, regardless of membership level.

Winchester Model 70 Serial Numbers

While browsing Gunbroker.com I came across a Super Grade Model 70. /descargar-la-biblia-reina-valera-1995-gratis.html. After contacting the seller requesting the date of manufacture, he replied with 'The date code on this firearm is ZT, which makes its year of manufacture 2016' I then asked for the serial number and he sent me this: 'The serial number on this firearm is 35GZT04331'. This information is no substitute for obtaining a Winchester Factory Letter from the Cody Firearms Museum (available for certain models and serial ranges) which in addition to the Serial Number Application Date, normally provide the original Received In Warehouse Date and Date Shipped from Winchester factory. I have a 2006 model new haven Win Model 70 in 300 wsm that has the balck packmyr pad, but not sure when Winchester started putting these on model 70's. Any help greatly appreciated on dating the year made would be greatly appreciated. Side note - as far as I know Winchester put serial numbers on all their model 70's. Even those manufactured prior to 1968 when a law (GCA 1968) was enacted that said all guns need to have serial numbers placed on them as part of the manufacturing process. When did Winchester start and stop this series, what calibers was this series made in, and what models were made. I have an early model 70 classic 270, Super Grade, serial # G18180, and a feather wt, 7mm-08, serial # G40001. I really like them both especially because of the old claw extractor, and controlled round feed as in the pre-64 model 70's. /philips-sv23-driver-download.html.
