Large Unused British Rail Guards Signalling Railway Lamp

There is a removable red filter which leads me to believe it was used by the guard on a loco circa 1950s -70s. It has 2 thick bullseye lenses which are intact no cracks.

The paintwork is good with just a few chips here and there, also some age related rusting to interior but not excessive. Please study all pics as i think you will struggle to find one in better condition.
