 Unknown until the 20th century, this concerto was later discovered to be a spurious work by Marius Casadesus.It was given a new number in the sixth edition of the Köchel catalogue, K. Anh.C 14.05, as part of the Anhang C designated for spurious or doubtful works which have been attributed to Mozart at some time.First published in 1933 in a version for violin and piano, the concerto was said by Casadesus, the "editor," to have been arranged from a manuscript by the ten-year-old Mozart, with a title page containing a dedication to Madame Adélaïde de France, the fourth daughter of King Louis XV.
