Seven-stringed bass viol with narrow festoon outline and detachable neck which can be housed inside the body of the instrument.

The bridge is located between two small inlaid raised ledges. Pale golden varnish. Ribs of quartered plain walnut. Back two-piece, of book-matched walnut, with painted purfling; there is a line of inlay along centre line with decorative inlays at top and tail. The hookbar is carved and let in between two narrow chequered strips. A door is formed from a section of the ribs of the lower bouts, turning on hinges of folded and riveted sheet brass and fastened with two hooks and eyes. The fingerboard is inlaid with chequered strips of walnut and ?plum; the tailpiece was made in the 1970s (as was the bridge) by Dietrich Kessler in similar style, replacing a non-original one.
