MSA Comfo-Cap Miner’s Helmet

Description (Brief)
This plastic Comfo-Cap brand miner’s helmet was manufactured by the Mine Safety Appliance Company of Pittsburgh, Pennsylvania during the 20th century. The MSA Company first registered their trademark for the Comfo-Cap in 1935 and continues to produce the helmet into the 21st century. The front of the helmet has a bracket for either a carbide mining lamp or electric lamp. This mining helmet has a low profile to avoid bumps, hard plastic to absorb impact, and its flat front served as an excellent mount for mining lights.
