Quiz Night

It's Thursday, it's seven o'clock (-ish), it must be time for another quiz...

Following on from last week's starter for ten, this is another close-up of an every day object wot I found.

Last week's was identified rather impressively by acronymphomania and this has propelled him to the top of the scoreboard (way out in front, all by himself, clear of the chasing pack, no-one in sight. Literally, this is only the second one).

The only clue is that, as last time, it's something from around my desk at work...
