MK Toughplug with red lid and BBC logo. Pictures and text provided by Loz Pavier.
Often seen branded as 'Hospital Property', this example has the BBC logo embossed in it, indicating that it would have been provided to the BBC and attached to their equipment originally.
Wraparound terminals are used, as in Modern MK plugs, along with the self-gripping cord grip.
A 3a red Ever Ready fuse is fitted, feeding a two core power cable.
