What affects the value of Red Comet Fire Extinguisher?

• The color and clarity of the glass, with vibrant red or clear examples being most common.

How to Identify Red Comet Fire Extinguisher?

• Look for the 'Red Comet' branding etched or printed on the glass bulb.

History of Red Comet Fire Extinguisher

Manufactured by the Red Comet company of Littleton, Colorado, these 'fire grenades' were designed to be thrown at the base of a fire or mounted in a spring-loaded bracket that would shatter the glass when a fusible link melted. While popular in the early to mid-20th century, they were eventually discontinued due to the toxicity of the carbon tetrachloride gas they released when heated.
