Anything is possible, but, in this case unlikely. You could go to proofhouse.com and go through all the serial numbers for the different rifle models.

The Cody Firearms Museum - they might be able to assit you.

Will need a serial number from the rifle to determine the age.
To determine the age of a Winchester firearm, including those with a specific serial number, you would typically refer to the Winchester serial number records, which provide year of manufacture based on the serial number. The serial number itself can give insights into when the gun was produced. If you have the specific serial number, you can look it up in historical references or databases dedicated to Winchester firearms to find its date of manufacture.
Virtually impossible to determine caliber by just the serial number.
