The previous owner found this
black with tarnish, in a vintage instrument shop in Philadelphia.
During restoration, this beautiful silver instrument slowly emerged.
Note the "backward" layout of the non-Briccialdi thumb
Closing the upper key only give B natural, adding the lower gives Bb,
but more logical than the standard Boehm flute. The 1867 system
also sounds an open D without added trill keys.
RIGHT: Note the Dorus (normally open) G#. All left hand fingers down gives a G, lifting the little finger gives G# -- again, backward from the modern fingering, yet again, more logical in that the more fingers down, the lower the note. This system also allows a truer E3 to sound without added mechanism of split-E or high E facilitator.
RIGHT: The logic of the open G# doesn't carry through to include an open D# -- too many objections from the old fogies, no doubt. Note the elegant, flowing R4 touches for D# and C#.
ABOVE: The close-up "clamshell" shows the cradle supporting the low C roller hidden beneath the C# touch.
The 1867 Patent flute is in some respects superior to the Boehm flute that has become standardized today. A major drawback is the increased complexity of the mechanism. However, once it is properly set up, it is very robust and stable, requiring minimal adjustment -- almost, but not quite, exactly unlike the Windows 98 operating system.
