Guys, I have a question concerning the Western Bowie knife. I have just purchased one that has no letter date code. Stamped on the blade is has Western, centered under that is BOWIE in all caps and centered under that is USA. There are no markings at all on the hand guard. The blade is well used and has been sharpened several times. Can any of you take a guess of the time period that this knife was made and could there be anything special about it? Thanks.
