Many thanks to SWLing Post contributor, Gary (W4EEY), who shares a link the following archived documentary on the BBC World Service from 1982:
The SWLing Post
Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
The star of this fascinating video is the studio microphone. Back in those (1982) days no way I could find the answer in 2 sec, but today just to crop a print screen and google will find

Great video. Thanks for sharing, Gary!
I think the BBC World Service is one of Britain`s finest exports and the Free World should be very grateful!
I listen to the BBCWS 2 hours each day through their Newshour program not including other coverage.
The World Service is one of the most trustworthy news sources that I know in the World and I have been a devoted fan for the last 50 years!!
