Grand Piano by Graf, C

The instrument is triple strung except for the bottom seven notes, which are double strung; the lowest sixteen notes (of brass wire and brass spun over steel) are mounted on a separate bridge and nut; the Viennese action is of the most developed type, with spring-loaded escapement levers, an escapement-lever rail, hammer check rail, brass kapsels, and leathered, wedge-shaped dampers suspended over the strings by a leathered rack; the hammers are covered with multiple layers of tawed sheep skin; all of the damper and hammer leathers are original and in very good condition; the key and action cloths are all original, though there is moth damage in some areas.
