Two German Hunting Horns. Clewing Pocket Hunting Horn in Bb. Furst-Pless Hunting Horn in Bb. 

BRASS FROM THE PAST: Two German Hunting Horns.
The Clewing Pocket Hunting Horn or “Taschenjadghorn” is in the key of Bb and wrapped in green leather. It is coiled six-times around in two layers and fits in the palm of my hand. Made in the 1950s by B&S (Blech & Signalinstrumentenfabrik), Markneukirchen.
The Furst-Pless Hunting Horn or “Jagdhorn” is in the key of Bb and wrapped in green leather. Furst-Pless signifies the origins under the late 19th century Prussian rein of Hans Heinrich IX, the “Furst Von Pless” or Prince of the duchy of Pless in Upper Silesia, a region of Poland today. He oversaw the hunt for Emperor Wilhelm II. It is double-coiled and probably made in the 1960s or 70s by Bohm + Meinl, Geretsried. Listen to sounds from the past. Probably 70 years ago more or less.
