I read that as DAF 44 the first time round
thought they'd be a bit impractical and not that thirsty...
I did a week of work experience at BBC Ealing Green film studios when I was at school. Was in their electronics department fixing Nagra tape recorders and the like.
At the end of the first day I put my mug on the shelf above my bench and went home..
Came in the next morning and the cup was under the opposite end of the shelf, smashed.
Couple of the other guys started laughing about the newbie putting his cup on the shelf so I asked what the joke was. They took me down to the basement where there were two rather large ship engines. We're not talking Hotel21 size here but they were the biggest engines I've ever seen. Probably 12 or 16 cylinders inline, 100 feet long with huge tappets bobbing up and down on top.
Turns out the studio had these installed to power lighting generators back in the good old days and they'd never got round to getting a decent mains feed installed so they were still in use.
.. and the vibration was such that anything that wasn't phyically tied down in that building had a habit of wandering off if you didn't keep an eye on it!
