Turner and Schuppanzigh's Beethoven

I am searching for two out of print recordings:

1) The Turner Quartet's recording of Beethoven Op 18 Quartets
and
2) The Schuppanzigh Quartet's recording of Beethoven Op 14 No 4 and Op
59 no 3

If anyone has these and can let me have an mp3 (or better still, flac)
or can send a link if these are  already online somehwere, I'd be
grateful. Feel free to contact me ofline.
