  Gem Brass Back.jpg - GEM BRASS - Brass lamp marked GEM in raised letters on top, with hook and cap braces, 3.5 in. to water door, 2 ½ in dia. brass reflector, mfg. by GrierBros., unfired condition; ex-Bob Schroth collection (The Grier Bros. Co. was founded in 1839 in Pittsburgh, PA to manufacture miner's equipment. By the 1880s the company was very active in the manufacture and sales of oil wick lamps with branches in Hancock, MI and Dubois, PA. They produced a line of face and driver's wick lamps for both oil and Sunshine fuels including the popular STAR brand in a shield trademark (check out the Grier lamps in the oilwick lamp photos). As wick lamps started phasing out with the increased use of carbide lamps, the company started producing carbide lamp models perhaps as early as 1910. They marketed at least 26 different numbered carbide cap lamp models. In 1924, the Grier Bros. plant and product line was purchased by the Gem Manufacturing Co. and a year later a product line of carbide lamps with the GEM product name as shown here was introduced that led to at least 18 different GEM lamp models being advertised; see Pohs, Miner's Flame Light, pp 245, 429-434)
