"More spectacular was the mark-up on a rare viola by Giovanni Paulo Maggini, named the "Dumas" after its original owner. It was valued by Biddulph at £200,000 in 1992, even though he had in 1990 valued two lesser Maggini violas for another client at £300,000 and £400,000. Although the estate agreed to sell the Dumas to Howard Gottlieb for £200,000, instead James Warren bought it for that price, together with a Guarnieri violin for £150,000, after Gottlieb allegedly discovered flaws in the instruments.
Although Biddulph claims to have doubted the authenticity of the scroll on the Dumas - doubts confirmed by WE Hill's recently published records - Warren had none, and promptly valued it at $1m, then consigned it to Bein & Fushi, who sold it as 'perfect' three months later for £750,000."

"As a specimen of Maggini's violas the Dumas instrument may confidently be pronounced unsurpassable. It will bear comparison with the finest violas of the other great makers."
