Handel's 16-tone organ again

On the Foundling Hospital organ, from the 1895 edition of the Grove
Dictionary of Music and Musicians article on "Temperament":

"Here the keyboard was of ordinary form, without any extra keys; but by
means of a special mechanism four additional notes, Db, Ab, D#, A# could be
substituted at pleasure for C#, G#, Eb, Bb of the usual series. Close to the
draw-stops on either side there was a handle or lever working in a
horizontal cutting, and having three places of rest. When both handles were
in the mid position, the series of notes was the same as on an ordinary
instrument, namely
Eb-Eb-F-C-G-D-A-E-B-F#-C#-G#;
but when the handles on both sides were moved in the outward direction, the
Eb and Bb pipes were shut off, and the D# and A# were brought into
operation. . . ."

> Eb-Eb-F-C-G-D-A-E-B-F#-C#-G#;

The second "Eb" should be "Bb".
