This is a very nice Colt knife.  Circa 1970's.  The knife is a Barry Wood design swing lock folding knife.  It is in great condition for its age.  This knife was not previously carried. It is out of a collection.  There is no box.  The satin finished blade shows very minor signs from opening and closing.  The knife hasn't been resharpened or altered.  There are no scratches from cutting through things.  The knife functions flawlessly.  The leather sheath is marked with Colt's symbol and is also in very good condition.  This would be a great addition to a collection.   Please look at the pictures.  If you have any questions please feel free to ask.
