[amsat-bb] Historical OSCAR 7 Recordings?

This may be a bit of a long shot, but I was curious if any recordings still exist of two unique transmissions made via OSCAR 7.

1. The National Air & Space Museum dedication speech made by President Ford and rebroadcast via OSCAR 7 on July 1, 1976.

2. The codestore message congratulating Queen Elizabeth II on her Silver Jubilee, transmitted on June 5, 1977.

Thanks and 73,
