Vintage Ever Ready Fish Eye Torch

An interesting pre WW2 Ever Ready 'fish eye' torch, an unusual looking item with a bulbous glass ball lense to amplify the light, marked to the bottom with Ever Ready made in England, it pops open at the bottom to fit the batteries and the top I assume to change a bulb, it comes in good order for its age with signs of use and is lacking a bulb and wires inside. It measures 5.5 inches long.
