The overall condition is good condition.  It has been used but still has plenty of life left.  The barrel doesn't have any rattles or cracks.  The end cap is snug and issue free.  The connector has stress marks but is otherwise firm and doesn't wobble.  The knob is good, and the grip is original and worn.  You may want to replace it.  Please see pictures.
