Shown here is something a little new for me. It is a screw-tip, but the tip has an external screw that screws into the collar. This horn is patterned after the LeHigh County horn shown on page 128 of Powder Horns: Documents of History by Tom Grinslade. My horn is slightly different from the original horns. The horn shown here has a threaded collar into which the tip screws. However, the original horn would have had a collar that slid over the throat of the horn with the threading to accept the tip in the throat of the horn itself.
