In the late 1920’s, Estey Organ Co. of Brattleboro VT, introduced this small, three rank organ.   It was offered in this design, or as an upright piano style.

Both models contained three ranks of pipes.  Through the use of Haskell pipe design, a full 16’ pedal stop could be contained in the limited space.

A sound sample from an Estey site can be heard here.  I can’t give credit as I don’t know the site owner.
