Where can I find a hand crank camera zoom lens?

I know that is specific, but does anyone know a good video camera (microphone, or more than 15 x optical zoom) Zoom with a crank? And this is not the type of device that is when you walk into Radio Shack that no camera take pictures and videos, but as a smaller version of the film cameras with the crank, the zoom? I have a photo alone, but I read that they had those things for the zoom.

Can you show us a picture? I do not remember seeing anything on a crank that the camera … had a handle on some of Zoom The "original" lens used in television cameras in the studio (which weighed more than 1,000 pounds). These rods were removed quickly from the camera handles the operator can control the zoom and has not had to use a wizard.
