Sold with the certificate of D.R. Hill & Son, Great Missenden, dated 14th March 2002, together with a letter of the same date stating that the instrument was sold by W.E. Hill & Sons in 1958. The instrument is also sold with the certificates of Emil Herrmann, Easton, Connecticut, dated 4th December 1959, and Jacques Francais, New York, dated 6th July 1967, both attributing the violin to Giuseppe Guarneri "del Gesù".
The instrument is also accompanied by a dendrochronological analysis by John C. Topham, Redhill, dated 18th September 2002. Interestingly, this report notes that both sides of the table significantly match a variety of fronts from violins made by Antonio Stradivari, particularly those made between 1717 and 1723. Topham notes that the strong similarity of the grain makes it very likely that the pieces from the front of the Guarneri came from the same tree as the Stradivari instruments.
