This horn has extensive engraving consisting of primarily floral patterns along with a single masted ship and the inscription "JOHN MIXER/HIS HORN THE/YEAR 1777/1777." The base plug is lightly domed, and the throat and spout are octagonal with a round midsection with raised rings as well as an scalloped edge on the throat. The included appraisal from William H. Guthman of Dutchman Americana states, "After checking Connecticut, New Hampshire, New York, Rhode Island and Vermont Revolutionary War rosters I have come to the conclusion that John Mixer was from Massachusetts and served in Capt. Lawson Buck minster's 2nd company, Col. Abner Perry's Mass. Regt. The Massachusetts rosters show him serving from July 30, 1780 to Aug. 7, 1780., marching to a Rhode Island alarm. Records of militia service are fairly incomplete so his early service does not appear., the records probably not surviving. There are Mixers listed in New Hampshire and New York, but not a John Mixer. This is probably your man." A small display stand is also included.

Fine overall with mild age and storage related wear on the horn, including some small flakes at the edge of the base. The base plug has moderate wear and a later tack. The engraving and inscription remain clear. This is definitely a very attractive Revolutionary War 1777 dated powder horn.
