V. F. Červený & Synové

Červený established his workshop with four employees in Königgrätz, now Hradec Králové, in 1842.

By then a family business known since 1876 as V. F. Červený & Synové (V. F. Červený & Sons), it was a prolific operation supplying thousands of instruments annually to the Imperial Russian Army, as well as the royal household after receiving the k.u.k.

[2] In 2016, British manufacturer Geneva Instruments purchased both the Červený and Amati-Denak businesses and continued to operate them as subsidiaries based in the Czech Republic.

[3] In 2020 however, the Červený factory in Hradec Králové was closed down due to the insolvency of its sister company, Amati-Denak.

In addition to standard orchestral brass instruments (trumpets, french horns, trombones and especially tubas) it manufactures less common instruments such as piccolo and bass trumpets, Wagner tubas and cimbassos, as well as rotary valve trombones for Italian opera and East European orchestras.
