This is what I believe to be a Kuhnl & Hoyer Bb Furst-Pless Horn 1304 G - hunting horn. Horn is brass with a chrome ring on bell. Horn has a nickel slide with a Meister Anion Koln 7 C mouthpiece. It has a very nice green leather wrap and strap. Included with this horn is a players book, Der Jager und sein Horn, by Alfred Eisenschink in German.
