A 'keyboard' from the 1810's or earlier sitting on my grand, or 'keyboard' as they're referred to these days. The little 'harmonium' belongs to the 'reed-organ' family probably dating from the late 1700's (Thanks Mieke!) An important detail are two 'knee swells' - instead of bellows the lateral pressure of the knee on a projecting piece of wood it brings the action of the full power of the instrument, so that's how it works!
