I picked this horn up at a recent gun show. The horn is 12 inches around the outside curve and the base is 2.5 X 3 inches. The base plug is domed and hand carved with a knife. The spout has a deep groove cut for the thong which is most likely a replacement. There are what appear to be "chatter marks" from the horn being scraped with a knife in the horn making process on many spots on the horn. Would be great if they could talk.
