Although Erard was the biggest piano manufacturer in Paris, it were the instruments of Ignace Pleyel that had the preference of Frédéric Chopin. To compete with the concert grands from Erard, Ignace Pleyel built two concert grands with seven octaves in December 1842. The oldest remaining instrument is the piano with number 9872, dated from 1843. This instrument is classified as 'Monument Historique' in France. In 2007 Chris Maene was able to buy an identical instrument, but finished as an Art Case, for the Chris Maene Collection. The purchased instrument has the number 9861, also dating from 1843.
