His last etude-tablau was based off an oriental march, if that's what you mean.You can find it at sheetmusicarchive.net... op.39 no.9.
i think i found it. this piece is called "oriental sketch".it was on the now defunct piano.ru site. luckily i have the whole website on my hard disk. it has no opus number, but this is in b flat major. take a look anyways.EDIT: maybe not. the year says 1938. this is al i have found with that name.
