Brass post horn – ZIMMERMANN, Jul. Heinr.
This brass post horn was made by the Julius Heinrich ZIMMERMANN (1851-1922) company. Zimmermann was an extremely successful entrepreneur in the manufacture of musical instruments and also publishing. He had branches of his company in St. Petersburg, Moscow, London, Riga and Leipzig.
This particular instrument is stamped ‘LEIPZIG’, where he set up his business in 1886. We can date it to around the end of the nineteenth century. This German post horn is made of brass with circular coils. Its mouthpiece is also crafted in brass. It features an open tone-hole, known as a Quartloch [fourth hole], which was used to transpose all notes of the natural scale a fourth higher.
