As pointed out to me, #s 19 and 20 are missing from this file. #20 is present on the K. 430 page, but # 19 in the 1895 edition seems to be missing wholly?
No.19, according to WorldCat, is not the Pastorale K.9 transcribed to E minor at all, but a Pastorale in E minor by an "anonymous composer". In the interests of clearing this up, I've put in a request to borrow the copy of this that is claimed to be at my local University Library. If all goes well, I'll make a PDF of #19 and upload it (not the Tausig arrangement of it as also edited by Buonamici and published a few years later also by Schirmer) and upload it either to the K.9 page (if it is that work) or to some other appropriate page...
The only major differences between "K.9" here (reading up to the first repeat anyway) and the Longo L.413/K.9 is that the trills are written out in Buonamici's edition where they aren't in Longo. I'm guessing they're the same piece entirely. Adding the PDFs of nos.19&20 here in a separate bar, having scanned them, unless this isn't the right page for them, in which case I'll add the PDF of 19/K.9 -there-... - the PDF of Buonamici's version of 20 is already @ the Di Ballo page.
