For your consideration are these carbide miner’s lamps, circa early 1900's. There are two lamps in this collection. The first lamp shows its manufacturing from Lamp Dewar and shows the Carbide canister on the bottom detachable. This lamp was made by the Dewar Manufacturing Co. of Brooklyn, New York, who produced carbide mining lamps from around 1914 until the late 1930’s. Dewar was well known for its “I-T-P” (It’s Trouble Proof), Sun Ray, and Dew-R-Lite lamp brands. The second appears to be a bit older and has a refillable nozzle without a canister and it is unmarked. The condition of these carbide miners’ lamps is fair, with oxidation and wear consistent with their age; the smaller Lamp Dewar lamp is missing the right angle attachment for fume regulation. The measurements of these carbide miners’ lamps are 9" x 4" x 4 1/4" and 9" x 4 1/4" x 5 1/4".
