Photograph of interior view of unidentified factory, showing a single worker standing near the turbines, ca.1935. To the left, a single man can be seen standing near a long line of gears extending far into the background. At center, a large cylindrical tank can be seen. The tank connects to two separate pipes that run along both sides of the line of pipes. Additionally, another pipe extending from the ceiling also runs along the upper portion of the gears. Along the top pipes, several small circular valves can be seen. Along the lower pipes, smaller pipes can be seen extending to the machinery beside each gear. Each of the gears are large cylindrical objects with a single ride on their sides. A small protrusion can be seen along their otherwise smooth frontal surface. The man stands over these gears holding a small object in his hands. To the left of the man, a spool of wiring can be seen. Similarly, a large spool of wiring is visible in the extreme foreground to the right. To the left, additional pieces of machinery can be seen. In the extreme background, several building supports can be seen near large lines of machinery.
