From David Atwood
David Atwood (camera) and Steve Potter (dolly) shooting a 1967 production starring Lotte Lenya (Dave Davis directing). The monstrously unwieldy and notoriously unstable TK-60 camera, sporting a turret of four fixed lenses, is the last black and white model that RCA ever made.
These guys are operating the equally unwieldy (though beloved) Fearless Panoram Dolly, which was modified at the station for the 1959 series A Time to Dance. It was upgraded to a "long-tongue" version from its former "short-tongue" RUB (rather useless behemoth) status.
