All 3 look like reproductions to me. The top one is possibly an old repro from the 30's made by Mack Tussinger. He made lots of repros like this from broken points. The Dalton looks new because of the forward pointing serrations and the fact it has been heat treated. Dalton makers never heat treated their flint. The bottom point is suspect simply because of guilt by association. The top point is collectible, lots of people collect Tussinger points. The others not so much. Gary
