On the upper photograph the G sharp lever operates directly on the key
to the left and the
two keys on that photograph operate entirely independently. This flute
has an offset G
mechanism but an open G sharp is just as easily fitted to in line G
mechanisms.
The Lower Photograph illustrates the total lack of a separate G sharp tone hole.
Also can be seen the reverse B / BFlat Thumb
keys which are logical but not necessarily
common or essential on an open G sharp flute.
