An authentic mid-20th-century flame safety miner’s lamp manufactured by The Wolf Safety Lamp Co. in Sheffield, England, and imported for South African mining operations by Green & Sons Machinery (Pty) Ltd. The Type 7RMBS model features an internal re-lighter, a magnetic lock interface, and a bonneted safety design tailored for high-draft ventilation underground. Bearing double certification plaques—including the G.M.E.F. No. 1 approval mark and a metal asset inventory tag numbered "107"—this piece serves as an exceptional historical example of subterranean safety engineering. Shows honest vintage condition with age-appropriate surface wear, minor surface oxidation, atmospheric tarnish, and minor pitting on the steel bonnet and base. All metalwork remains structurally sound and intact. Clear cylindrical glass shade is complete with intact Pyrex M&Q markings. Plaque stampings and factory engravings remain fully legible throughout. imensions: 29.5 cm (H)
