19th century miner's oil lamp - wrought iron

This superb nineteenth-century miner's oil lamp was used to help miners to see and also to monitor the amount of oxygen in the mine. It was designed to be suspended, hence the handle and loop at the top. To refill with oil, the little bird-shaped nut is unscrewed and the little lid lifts off. A well-used lamp - there are still traces of oil inside. It is beautifully made from weighty wrought iron.
