Description
Description from back of photo: "The average Christmas tree of today has only one leg as show in this picture. The fittings on this Christmas tree do not have to stand the pressures shown in the older style tree and are more economical to install. The little pet cock permits the pumper to take a sample of the oil coming from the well."
