This is a photograph of Glyn Pits taken in 1905. There are several things the reader should note: For example, the two winding ropes, were flat and of woven construction. One of these ropes leaves the engine house through a hole in the roof, while the other through a slot in the front wall between two of the three wooden bracers leading up-to the headgear. These bracers were necessary to counter the pull of the engine against the weight of the cages and ropes in the shafts. Note the immense size of the headgear in the photograph, said to be fifty feet high to the pit-head rope-wheel spindles. The distance between these headgear wheels or pulleys limited the distance between the mine-shafts, which in this case, were just 31 feet centres The 'Down-cast' shaft, being the smaller of the two at just 9 feet diameter, The 'Up-cast' being larger at 11 feet diameter with the extra size needed to accommodate the pump rods and water pipes. Although the shafts were 31 feet apart, this left only twenty feet separating the shaft walls. As can be seen, there are two stacks, the stack on the right was for the two Cornish boilers. which supplied steam to the beam pumping engine, while the stack on the left was for the boiler in the basement of the winder house. This stack also appears, from the configuration of the pipe-work in the basement, to have taken the exhaust steam from the vertical winder. The Logo 'E.V' on the side of the trucks stood for the 'Ebbw Vale Steel, Iron, and Coal Company'.
