The instrument is rosewood with german silver keys, ferrules and crook lining. In common with most German instruments of this period, most of the keys are levers. All sections are stamped with bird on branch motif / “O MOENNIG / LEIPZIG” / monogram of M superimposed on a circle. The crook is curved in an arc with a metal knob on each side above the cork presumably to add grip when it is removed.
The instrument has a tuning-slide to enable the player to use the instrument at different pitches. However, it is only partially effective.
