The Clarabella I have is indeed open and has its mouth on the narrow side. I think it was from a Nicholson and lord instrument.
The Rohr flute is in Metal with Long turned and Pierced Wooden stoppers and the Claribel Flute is a Binns manufactured stopped metal pipe.
The Binns chorus on it original pressure was rather bold but it performs well on the reduced 3" wind.
The instrument is going in a 80ft long stone built 2 storey barn
regards
