This is a "Baby" Wolf Company Safety Lamp manufactured in the early 20th century. The "baby" name denotes its smaller size, and the "permissible" on the plaque indicates that this lamp was approved by the United States Bureau of Mines. The baby Wolf safety lamp was manufactured for mine bosses who only needed lamps for infrequent, brief periods.
