Vintage Winchester USA #1920 Bone Coke Bottle Folding Hunter Knife 1919-'42 Exc For Sale

This is a vintage Winchester Trade Mark USA pattern # 1920 Coke Bottle Folding Hunter style knife made between 1919 and 1942. It measures 5 1/4" closed and has pretty brown bone (bovine bone) handles with center pin cracks on both sides. These are very tight cracks and hard to see. The front crack seems like it goes both ways from the center pin at about a 45-degree angle to the handle edge. The back crack looks like it starts at the bottom of the handle and goes at an angle to the center pin and goes right for about 1/2" above the pin. I tried to show them in the photos. The blade has been lightly used and sharpened with good snap action and half stop. It is tang stamped WINCHESTER over TRADE MARK over MADE IN USA and rear tang numbered 1920. I included a photo of this knife from a price guide book. Overall a rare and valuable old Winchester knife in excellent condition. Thanks for looking.
