Found this wrench (about 8 inches long) near an old water pump station. I researched "types of wrench" and "antique wrenches" on the net and couldn't find any pictures like this one. Anyone know what this is used for? The other side has a six-sided nut wrench indentation just below the "star" section. Am I right in assuming the "star" section is used for a square nut head? How about its age?
