I have a 94 manufactured in 1950. Serial #1646707. So yours is probably a 47 or 48 model? I've got a Winchester dating book somewhere. If my wife would quit putting my stuff away I'd know where it is.

bullet placement is gun control
I read onetime that Winchester recievers were not assembled in order of serial number. This means that a low number is not always a old gun. maybe someone knows more about this i dont even rember where i read it.
