OOOOOOOOO nice . If only it could talk what stories it could tell! I collect Knives (bowies) mostly . I stroke and stroke and listen but only my imagination starts to work. David Crocket my hero and Jedediah Smith . I love the true stories of the Mountain Men .
If you can read the serial # you can find out a lot about the exact date it was made. I think the ivory bead can be a real addition to the value. I don't remember ever seeing or reading about that . Also kept in the org. condition generally the value only goes up. If you restore and reblue it will drop in value.
But if you don't plan on a resale someday I would restore it myself. This is just my opinion and as they say that and two dollars will get you a cup of coffee.
