This is a smaller version of the King Trombonium invented in the 1940’s by H. It was manufactured in 1948 and was the property of the State University of New York at Oswego. There are only two or three very minor dents but otherwise the instrument is in most excellent condition. In cleaning the Altonium I removed the old lacquer which should be replaced by a professional.
