The horn is in good condition from the photos. Plating seems mostly intact except at the hand-hold areas. Inside of bells is gold wash. A so-so case is included. This is a bid-only auction, with NO reserve, and the current bid is $700. (He listed before with a much higher price, so he learned that won't work, I guess). Because there is no reserve, this could turn out to be a nice buy!
