This is a vintage Estey pump organ. This portable, folding, collapse-able reed organ was originally used for “field” sermons or performances outside of a traditional inside environment. It is self-contained and light enough for easy transport. This 4-octave Estey features all original components and parts, including the often removed and refinished black exterior. A must have for recording studios, keyboardists and musicians desiring a wonderful sounding air organ, this is a great example to consider.
