Your answer helped me to figure out the differences between the two
editions:

- DG 419745-2, issued in 1961, has all three symphonies conducted by
Mravinsky, in stereo, recorded in London in 1960;
- DG 447423-2, issued in 1996 (Originals), has the 4th with Sanderling and
the others with Mravinsky, all in mono, recorded in Vienna in 1956.

Thank you for the information.
