Shank ?
I found three older 110's about a month ago at a garage sale
I would join BCCI ,Buck Collectors Club Inc.Great people full of knowledge.
The have a trade zone on their web page
You can contact Larry Oden ,thru the club he has Bucks on consignment
Check with your older hardware stores ,gun shops,they might still have some and ask them who was the Buck rep,salesman,people change jobs and some keep the old samples and picked up merchandise some even collect.
I found 30 such knives New in the box 5 weeks ago including two very rare Bucks and several with buck only on them. I got to view them Monday and with help from some of the BCCI members ,values were determined , now I have to wait until next Monday to see if we can make a deal. good luck in your adventure
