- Description (Brief)
- The Koehler Manufacturing Company produced this safety lamp during the 20th century. The lamp is marked “Permissible” meaning that it was approved for use by the U.S. Department of the Interior Bureau of Mines. This lamp employs a Pyrex enclosure to protect the flame from extinguishing, wire gauze in the top-interior to keep the flame from escaping, and a metal bonnet exterior that serves both purposes.
