Finished up this simple little octagon shaped priming horn. It used to be just a scrap of horn in my waste bucket, but I could see a neat little primer in it. It is about 6 inches long including the spout plug and is 1-5/8 inches in diameter on the butt end. Just the right size. The butt plug is lathe turned walnut, slightly domed, with concentric rings and the spout plug is ebony. I cut a groove around the horn for attaching to a bag strap.
