Stores ref. 5C/621. By Crabtree. 5 Amp/250 volt. White glazed ceramic bases with brown bakelite covers and toggle switch. Marked in black with Air Ministry King's crown marks and reference numbers. The switch is mounted to a metal plate via two metal bolts. As used throughout RAF station buildings. Perfectly useable but ensure you consult a qualified electrician before attempting to use. Not a showy as those with the brass domed covers but a fraction of the price. A little grubby but should clean up very easily. One more turned up in the stockroom whilst searching for something else! Stock code M18496.
