We bought a tomahawk (tradeaxe) from a reputable Indian artifact dealer. While we're sure the handle has been replaced, there is a sticker on it that reads: "Trade Axe (Tomahawk)1700's. Makers mark both sides. Chequagua Falls, Seneca Lake, NY". Along the rim it says "H. Jacoby Collection." On one side of the blade, there are two square with "IV" stamps in it. On the other side is a triangular shield with a "S" in it. Can anyone give me any information on this tomahawk?
