Photograph of a rotary drilling outfit, ca.1940. A man wearing a jumpsuit can be seen at left standing behind a circular-shaped machine reading, "[?] Stone Drill [?]", which is visible with a pole extending from the top of it. A large spool of cable can be seen to the right, while a cable extends from it toward the ceiling. The floor is composed of rough wooden planks, while metal walls are visible in the background.
