V.F. Červený is credited with inventing the Promovka or Primhorn in F alto in 1867. This horn was imported by Louis Vitak, sole authorized U.S. agent for V.F. Červený & Sons, as shown in his 1905 Catalog. It features the patented valve set with spring tension adjustment thumbscrews. |

(Above) The serial number 20183 is just 3 away from its companion F/E♭ single horn. The horn originally came with terminal crooks in F, E♭, D, and C, with the valve slides graduated for those keys (Left). |

The valve set retains the spring tension adjustment thumbscrews designed by Jaroslav Červený in 1873 but with the rotors mounted vertically in the usual way instead of horizontally as on earlier Červený models. The number 1438 stamped on the underside of the valve key saddle is apparently a part number. The same valve set and number appear on the companion concert horn. This is probably a result of Červenýs adoption as early as 1843 of American manufacturing methods including the use of standardized parts.
