We had one of those Chinese "Pearl River" Harmoniums once - I think Pete Coe had bought up a job lot of them and Mary bought one. We used it for one track "It's A Rosebud in June" on our first, home-recorded album Through the Groves. You can hear the result HERE (Ogg Vorbis sound file).
We then sold it to Johnny Adams and Chris Coe who used it for at least one track on Chris's album "A Wiser Fool".

Despite being a remarkable engineering achievement to make a harmonium fold up into a small rectangular box, it's still unpleasantly heavy to carry about. It's also half a semitone sharp. It was never gigged and we don't miss it.
