"The arms on this Violin are those of Victor Charles Antoine de Riquet, 2nd Duc de Caraman (born 7th February 1811, died 4th June 1868). He is erroneously refered to as The Prince Caraman de Chimay in the literature. Two quartets were ordered from Vuillaume in the mid-1860's, one quartet was made for the Count Basil de Cheremetoff and bears his coat of arms, the other quartet
was made for The 2nd Duc de Caraman de Chimay. Doring illustrates the Violas from each quartet (pp. 34 & 35). The Cheremetoff quartet is numbered 2602-3-4-5 and the Caraman quartet numbered 2609-10-11-12, ('Cello, Viola and two Violins respectively). The whereabouts of the present instrument (numbered 2612) was unknown to Doring at the time of publication of the issue on Vuillaume, although he notes that the Viola and Violin numbered 2611 were brought to the United States by Nathan Posner, ownership of that Violin passing to Sol Kinder and then Louis Feilner. Ownership of the Violoncello apparantly passed from Moennig to Paul Dennis."
