I have a powder horn that has several carvings on it. On one side is the date 1816 with a eaglehead above it,on the other side is a whole eagle.Also it has some scrolling with some type of metal inlay .The wooden end caps are put togather with a red resin that looks like tree sap.The horn is attached to a leather shoulder strap with 2 knives.One knife is a deer antler handle skinner, the other is a smaller patch knife with a turkey thigh bone handle. It seems to be really aged. What would this might be worth??
