A (more or less) working harmonium is Holy Trinity Church, Hethe, Oxfordshire is available for anyone who wants it. (Contact details here.)
Contact the parish to see it or collect it.
Holy Trinity is a lovely church, which thanks to an enterprising former Parish Priest has a very interesting 18th century chamber organ (in need of some restoration). For some reason it also has this harmonium, which takes up a good deal of space in the tiny choir loft.
Someone: give it a home!
