It must be discouraging to post a question and to get no response!
First, Vincent Mouret's on-line Mahler discography lists two Kegel M-1 recordings, neither of which was in 1981. The Weitblick recording (of Kegel and the Rundfunk Sinfonie Orchester Leipzig) was on May 9, 1978. There was also an Eterna recording (of Kegel and the Dresdner Philharmonie) on November 5-8, 1979.
It appears from what you say that you have the earlier one. I have the later one and have listened to it and thought the second movement somewhat different from what I recalled from others. So I listened to several other treatments--Abbado, Farberman, Guiliani, Muti, Colin Davis, and others--and found that Kegel and the Dresden were distinctly slower, more hesitant in the early part, and perhaps a bit off in the horns from time to time.
Wish I had the Weitblick issue, but so far it has escaped me.
Does this help any? At least, you have a response.
