Douglas Cox Violin Opus 845 ~ “Koff” Vuillaume Guarneri


The violin bears the facsimile label “Jean Baptiste Vuillaume a Paris / 3. rue Demours-Ternes ” and on the opposite side the label “Douglas C. Cox, Brattleboro, Vermont, 2014, #845” and is branded and initialed on the inside. It is patterned after a Vuillaume enlarged Guarneri pattern instrument, formerly in the possession of Robert Koff. It is built of well aged North American grown wood. The back is cut on the quarter from two pieces of New England maple with medium-narrow flames descending slightly toward the bass side. The neck and ribs are of maple similar to that of the back. The table is of two pieces of Engelmann spruce from British Columbia of mostly even wide growth. The varnish is of a amber- brown color over a golden ground and is shaded and imitated. The fittings are of rosewood.



Robert Koff’s violin was made in the Paris workshop of Jean Baptiste Vuillaume, probably around 1860. He played this violin in the Julliard Quartet for several years and he considered it the perfect instrument, with a dark chocolaty quality and plenty of power and punch.
