Ferdinand and Andreas decided to equip the instrument with a set of the two tuning slides (D and E) and two 2nd valve slides. Then the Soprano helicon needed a lacquer and Melton Kunstgravur. By the end of September 2006 the first Soprano helicon was completely finished and sold to Irena Nadler who is now the first regular student in the world, learning this instrument.
