good technological history of classic hollywood for the class

trying to locate this reference to the bazaar scene in GWTW being shot on a turntable, and came across this excellent article on techological innovations rom the silents through the height of the studio system.

below is a picture of george cukor laughing in delight at this turntable shot -- with clark gable and vivien leigh waltzing - in what would turn out to be his last day ont he set of GWTW. He was fired at the end of that day, and Vivien Leigh and Olivia de Havilland went over to Selznick's office in their full Civil War widow's costumes to beg him to change his mind, but selznick refused.

The three week's of Cukor's work, and for another month afterwards, was all done by Lee Garmes, who was also then fired. So lee garmes must have done this turntable shot - which i can't seem to find a reference to, let alone a picture of, anywhere - all this for one reference in my essay. this is beginning to amount to stalling.
