Hullo once more,

I've come across piano solo arrangements of the 3rd (and even the 1st!) movement of Rachmaninoff's 2nd piano concerto, but none of the 'Adagio sostenuto' movement.
Does anybody know if there's such a thing out there? I mean, an advanced transcription, not a paraphrase or fantasy, nor a simplified version of it, such as the one that can be found at IMSLP.
Yes, I've already looked for it myself, but so far no luck...

Cheers!
