A few parts of André's collection remained for a long time in private hands; hence, in 1948, when Hutchings compiled the whereabouts of the autographs, two (Nos. 6 and 21) were in the hands of the Wittgenstein family in Vienna, whilst No. 5 was owned by F. A. Grassnick in Berlin and No. 26 by D. N. Heinemann in Brussels; a few others were scattered around other museums.
Unha parte da colección de André estivo circulando por mans privadas durante moito tempo; ata que en 1948 Hutchings recompilou os paradeiros dos autógrafos, dous deles (as partituras dos números 6 e 21) estaban en posesión da familia Wittgenstein en Viena, mentres que o n.º 5 pertencía a F. A. Grassnick en Berlín e o n.º 26 era de D. N. Heinemann en Bruxelas; o resto estaba esparexido por varios museos.
