Chopin Fmi concerto

[Keybawd]

In Stirling's (Chopin's pupil) copy of the Second Piano Concerto, op. 21, Chopin rewrote the left-hand part in the second movement to fill in the harmony so that the movement could be played without orchestral accompaniment. This left hand part was printed in the 1932 Oxford Edition (Edouard Ganche) and, I'm told, in the Ekier National Edition. Does anyone have either of these? K
