[Mini truck, running study] Stylish lantern with emphasis on atmosphere! E.Thomas & Williams 

I found some information for you about your lamp, after i tried to find a copy of the leaflet that came with the lamp. This lamp is typical of lamps used in Welsh Coal Mines. The Welsh Miners’ Lamps were ingeniously designed over 180 years ago to alert coal miners to danger. It ensures the burning of a protected flame in the presence of explosive gas, by regulating the necessary supply of atmospheric air, and by allowing the products of combustion to pass through without igniting the gaseous atmosphere. If the atmosphere is so heavily charged that noxious gas enters the lamp, its presence will be indicated by a change in the length and color of the flame, and (unless there are exceptional circumstances), the miner has sufficient warning to secure his safety.
