Early Dumont Cameras: Configuration 2

Unlike the RCA cameras, the Dumont Iconoscope cameras had electronic viewfinders which were side mounted. This called for more equipment at the camera and this is one configuration of how that was done. I suspect the larger box is the camera control unit and the smaller one, the power supply. These are mounted on simple rolling dollies with rear steering. The cameramen have their hand on the focus lever. These were probably 50 or 75mm lenses. Dumont was the only one to use the ball type pan heads. This photo was probably taken in Washington in the summer of 1945.

On May 19, 1945, DuMont opened experimental W3XWT in Washington, D.C. In 1947, W3XWT became WTTG.
