Our invention horn is similar to the original Bohemian Instrument by Franz Stöhr, Prague from the early 19th century and, like that, is made of particularly thin brass. With the crooks, different pitches from C-alto to Bb-basso are possible. The very long tuning slide also allows historical tuning of 415 hz.

The instrument can be delivered with a decorated brass garland (picture) or rolled rim on the bell
