Thank you for this, Greta! However ...
... what you've done has resulted in a misrepresentation. This is not a rip of Radio Records RR 121.
The fact that it isn't but is labelled as such is going to lead to problems in the future when this home-made compilation of parts of two Mozart rips of unknown -- and possibly different -- pedigree is shared by others. Then it will turn into a falsification, misleading people into believing they've got something which in reality they don't.
I would like to ask you (and all downloaders here as well) to consider tagging these files according to their true nature, at least. This might leave a bit of a chance that not everyone who happens to receive them via downloads of downloads of downloads will entertain illusions about what they actually are.
It should also increase the probability that we may, at some point, be able to listen to a veritable recording of Radio Records RR 121.
PS I have deleted my download, as it is the easiest way of avoiding the problems described above.
