I have up for sale a 1978, NEW/OLD STOCK, 1975 CASE USA XX, 6249 , Copperhead( 5 -DOTS ), 3-7/8" LONG that is in MINT CONDITION and has never been sold, sharpened or carried before Friday's night's auction, to anyone else except myself, see pictures.This knife came out of a nearby HARWARE STORE OLD/NEW STOCK that closed many years ago due to the economy. This is one of 18 knives that I bought at this auction and all of them date back to the 1970's. I define NEW/OLD STOCK as any item that I purchase, NEW, from a store that has gone bankrupt and has never been sold to the public before. I would think that only collectors want to buy these knives since they are 33 to 40 years old! Contact me if you have any questions or want more pictures.
