Julius Keilwerth also produced a limited quantity of a trumpet called the 'Toneking 3000.' There may have been other brief forays into making other woodwinds or brasswinds, but no records are available as of this writing (February 2012). Most of these historical models were also available with different 'packages,' such as 'EX' ('Exklusiv') with more elaborate engraving, additional keywork, additional mother-of-pearl inlay, or drawn and rolled tone holes.
