"This instrument seems to have spent much of the 19th century in France. The first recorded owner is a M. Le Brun, who sold the violin to the Boutillier family. It subsequently passed to a Signor Signicelli, who was known as a violinist in Paris in the late 19th century. In 1922 it was sold by the Parisian dealers Caressa & Francais to Herr Otto Senn of Basel, and it has remained in the possession of his family ever since.
Otto Senn is also recorded by Doring as being the owner of the Samazeuilh Strad of 1717 (How Many Strads?, p. 214)."
