' :/Hailwooo‘3 ', Wmbustiom TU0E LAMP 64,000 ordered & supplied in last 18 months. Approved by both British and French Governments—that’s the Sterling record of the Hailwood . . Combustion Tube Lamp. Gives 1| to 1| C.P., it is cheaper and more reliable than an electric lamp— and it has gas de- tecting properties, too. Hailwood Combustion Tube Lamp is the ideal lamp for the miner. Because of the scien- tific principles upon which its construction is based, it is not readily smoked up, may be tilted without being extinguished, and is easy to clean. You will never be satis- fied with another lamp after you have seen the clear white light of the Hailwood. Our Circular gives the details. Send for a Copy.
