This powderhorn was made by my father in 1922. He was born in 1912. The story he told was that he bought it at the Chicago stockyards for a nickle while on a field trip as a Boy Scout. He scraped it smooth with his pocketknife and did the engraving/scrimshaw with a sharpened nail. The darkening was with India ink. It has never been used to hold black powder.
At the least, interesting.
