Ok, elsewhere we discussed at some length all about some of those LH works, and etudes. I just stumbled across a RH only etude by Kessler! 12 Virtuoso Etudes, Op.51, No.7 "Rhapsodic Etude for the right hand alone" which you can see the pdf of at: http://henseltlibrary.files.wordpress.com/2009/12/kesslerop-51etuderhapsodiquerh.pdf. This is a first for me. I never new of such literature.
