Related to Estey, I recall visiting what was left of the Estey Organ
Company in Brattleboro, Vermont, in the 1960s.  A nice old gentleman,
Hyacinth Reynaud, occupied one of a row of similar wooden buildings
that at one time had been factory units.  He gave me some parts and
literature.  Various pipes and parts were on hand for his little
business of working on reed (mostly) organs.
