JHOTH/GEORGE:
Ihave researched both Winchester, and any company begining with W and can find no such model number. As George indicated, Winchester did not make a shotgun forWestern Field.
In addition, I have checked my Stock cross reference and find neither Winchester or Western Field with that model number. Posibly you may have incorrectly read the number or mfg.
If you have a picture, maybe we could figure it out.
