The bell engraving reads: "SCHERZER Augsburg Modell Prof. A. Piechler". Key of B flat. Believed to be made in the 60's, it's an updated version of the long model Scherzer that Adolf Scherbaum made famous in the 50s with his numerous performances of the second Brandenburg concerto. This particular instrument was owned by Mel Broiles, the former principal trumpet of the Met Orchestra.
