Richard,
Regarding the double concerto we only have a score written by Brahms. All other material is either lost or destroyed by Brahms. There is nothing to proof te remark of Kalbeck.
The page with sketchs for piano are also known as A 121. This page also contains sketchs for opus 117 No. 2 and 3 and opus 120 No. 1
The page with sketches for orchestra are also known as A 122. This page also contains sketches for opus 121 No. 4
I think this too little.
Regards,
Arno.
