Jean-Baptiste VUILLAUME (1798-1875). L.A.S., [Les Ternes 25 April 1865], to Henry Vieuxtemps ; 4 pages in-8, envelope. Beautiful letter from the violinmaker to the violinist. "The price of my bows is thus distributed 25 fr. to the amateurs 20 fr. to the artists, and for the dealers who ask for them by dozen I leave them at 15 fr. which makes a dozen 180 fr. or a half-dozen 90 fr. It is impossible to establish them at less, and 15 fr. is about the cost price. You know that I don't pass lightly on the work and that everything here is done at length and well. Needless to say, if I have quite superior sticks, I don't sell them by the dozen. I sometimes make quite artistic bows, but I sell them at the best market price of 30 or 40 francs [...]. [Since you are satisfied with the strings, I will prepare an extra set for you. He will also prepare a bridge that he will adjust on the violin... Attached is a l.a.s. from Gustave Bénédit (1802-1870) to Vieuxtemps, Marseille 22 March 1859 (1 p. ½ in-8 on the letterhead of the Sémaphore de Marseille, envelope), about the study he is preparing on the question of the diapason and the problem of the old instruments and Stradivarius.
