I noticed on the engineering poster at Moorgate
that the multi coloured screws have a left hand
thread - anyone else noticed?

The old light bulbs that they had (have?) in Routemasters had left
hand threads - this was to stop anyone pinching them to use them at
home.


That sounds like an urban myth, bus bulbs are hardly likely to be
240v are they?


But someone inclined to do such a thing isn't likely to have the wit to
realise that they are probably a different voltage.
