WW2 low voltage blackout lamp

Got this from an LG member. Cool that it still works. This is an early one, probably used in WW2 with a bakelite base and white shade. Later on, they had a black base and coloured shades as they were still made as children's nightlights, not blackout lamps, and branded "Moonlamp". It uses a 6v torch lamp and a step down transformer, running on mains.
