The sellers comments:
Im not a Trapper guy, but always interested in such side tidbits of info like this. Anyone have some comments? Wasnt there something about older Case Trappers had a shorter rear bolster?THIS IS A VERY... RARE .... OLD KNIFE WITH.. LL BEAN,INC... FREEPORT, ME. ( STAMPED ON BLADE). THIS KNIFE WAS SHOWN TO A CASE MFG. REP. AT A KNIFE SHOW PROMOTING THEIR KNIVES. HE STATED THAT IT WAS A WELL BUILT KNIFE AND COULD BE A CASE OR A GERMAN MADE KNIFE, HE WASN'T SURE. THIS KNIFE CAME FROM THE ESTATE THAT STATED THAT LL BEAN WAS A GUEST AT HIS HOUSE WHEN HE TRAVELED THROUGH THE COUNTRY SELLING WATER PROOF BOOTS TO FARMERS AND WAS GIVEN TO HIM AROUND ==1921== AS A GIFT. AS A LOT OF FAMILY STORIES, THIS MAY OR MAY NOT BE TRUE, HOWEVER, THE NAME OF THE ESTATE OWNER'S LAST NAME WAS BEAN.
THE BLADES ARE APP. 3 1/2'" AND FOLDED UP. THE KNIFE IS APP. 4 1/4" LONG
THEIR ARE THREE COPPER DIVIDERS BETWEEN THE KNIFE BLADE LAYERS WHICH I AM TOLD MAKES THIS A VERY WELL MADE KNIFE. THERE IS A SMALL METAL INSERT ON ONE SIDE OF THE HANDLE, IT IS PLAIN WITH NO NAME AND LOOKS LIKE A CASE INSERT. ??
EXCELLENT CONDITION!!
I can see some dark spots on the blades but can't tell if its patina or pitting. Also, wonder what the handle material is to have that color.
