In the beginning of the 19th century, lived in Dinant a manufacturer of brass and woodwind musical instruments by the name of Charles Joseph Sax. On November 6, 1814 Antoine-Joseph, who was known as Adolphe, the first of his 11 children was born. At age 6 Adolphe was a prize apprentice in his father's workshop where he was appointed by King William I. At the age of 15, in 1830, he sent to the Brussel's Industrial Exhibition two flutes and a clarinet made of ivory, where they were highly regarded. He was 20 when he invented what we know of today as the bass clarinet. He relocated to Paris in 1842 where his new invention (the saxophone) was first documented in a publication by Hector Berlioz on June 12, 1842. Sax obtained the first patent for his saxophone on June 28, 1846. While in Paris, Adolphe Sax worked out of several different workshops in which the address was always stamped on each saxophone produced.

In what year would an Adolphe Sax saxophone have been made if it were stamped with the address 50 rue St Georges (there is more than one correct answer, but please respond with only one year)?
