My interest in reed organs dates back to my school days when two examples were found at my secondary school. They were no longer required and were donated to me. I recall that the makers were ESTEY AND BELL. I no longer own either of these organs.
American organs suck the wind through the reeds. European examples, known as HARMONIUMS, blow the wind through the reeds.
More recently, I have concentrated on folding organs, which were sometimes referred to as preachers organs. As the name suggests, they were intended for use where a portable instrument was required, such as use in the street. It is interesting to see the various methods used to make them collapse.
