Stores ref. 5C/621. By Crabtree. 5 Amp/250 volt. Brown glazed ceramic bases with matching bakelite covers and toggle switch. Marked in white 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. We had a small quantity of these, all of which sold quickly. Whilst packing the last order we found one more. It is grubby but will clean up very easily.
