There are some mold stains on the sheath and bolster.  This Hen & Rooster Hunter has a full tang and red deer stag handle.  Nickel silver guard and bolster.  The sheath is signed by Jim Frost.  I cannot explain this other than knowing Dad went to knife shows and Frost was a hero like figure to him.  There is at least on other HR knife out there with a Frost signed sheath, but no clear info on whether this was a unique thing or a production thing.
