The model number of the rifle should be stamped into the barrel by the Winchester name.
If the barrel doesn't have the Winchester name, the model of the gun, and the caliber it's chambered for stamped into it, it's not the barrel that came with the gun.
This will complicate the identification and you'll need to post a picture to get an answer.
The serial number on a Winchester rifle is only unique to the particular model.
Pretty much every model rifle Winchester ever made had one unit with that serial number.
It could be anything from a lever action 1895 to a model 12 pump shot gun.
If you're have both the model number and serial number, go to the website listed below to find the date it was made.
