Photograph of an unidentified machine at the Exchange Products Co. which makes lemon oil, etc., ca.1930. Two identical pieces of machinery stand against the wall at center with thick bases and cylindrical tanks that extend to long pipes near the ceiling. Each machine has a small wheel on its left side and another on its top. They each also have circular, metal panels on their right sides. Pipes extend from their tanks to the right while others reach into the foreground.
