Low Quality HMB mentions a piano solo reduction in 1870. I think this is it, since there isn't really a second piano part, just a sort of orchestral 2nd piano "cue", relatively speaking, written over the piano solo part- different from the usual 2-piano reduction in which the orchestral part is given equal size, at least, to the piano 1 part.
