I do have one question. The pump as found on the farm, had a "contains lead" placard that was way eaten up by rust. I ordered a replacement. But now I am questioning that it is likely the "lead" sign would have been added way after the pump went into service (probably 1928-35). I doubt there was a need to label fuel with a "lead placard" until way later. So IF that is the case, should I put the "lead" sign on or not? What do you think?
