Sold with the certificate of W.E. Hill & Sons, dated 30th December 1950, in which the violin is described as resembling the "Milanollo" of 1728; together with a letter from W.E. Hill & Sons of the same date, giving the history of the violin and stating that it had been "...loaned to the well-known player Ida Haendel who had hoped to acquire the instrument owing to its outstanding tonal qualities". Also accompanied by a letter from W.E. Hill & Sons, dated 13th July 1984, confirming the contents of the earlier documents and noting that the condition of the instrument had not changed in the intervening period.
The instrument is also sold with a dendrochronological analysis by John C. Topham, Redhill, dated 18th September 2002. This states that the youngest tree-rings measured on the front of the violin date from 1721 (bass side) and 1717 (treble side). It further notes that both pieces significantly cross-match a variety of fronts from other violins made by Antonio Stradivari.

"...the name 'Sleeping Beauty' is quite a recent epithet, which the violin only acquired in 2002 when the Times of London dubbed it that. The Times' lead was followed by other European press and by the auction house Christie's." – Alessandra Barabaschi
