Box organ with doors. The keyboard has boxwood and ebony key covering and slides into the case for transport; it is transposable to 392/415/430/440/460 Hz. The lid forms an adjustable music desk across the entire width of the instrument. The wooden pipework produces a particularly steady tone. The pipes have sufficient overlength to tune in all temperaments, and are easily accessible for quick tuning. Under each corner of the case are small wheels and (sliding) metal bearers; a light wooden transport case is supplied.
