Yeah I remember the lead swinger, it was a lump of lead on the end of a stick with a dodgy gimbal that used to break and send the lump of lead with a bit of a juniors blanket carreering off down the corridor!
RMR, the Big Bertha I was refering to was, as Claudel Hopson said, lit at 05.30. It was just a huge dixie full of water, that sat on the low gas cooker in the appt. kitchen, there were two turf fires with ovens either side of them that had to be lit and the gas under Big Bertha so that when we got up at 06.45 the 'waiters' could get breakfast ready. Some unscrupulous 'waiters' used to put loads of sugar in Stevie Currans porridge!
Right. Well what about burning your boots on the pot belly in the Courtmartial hut 'cos you'd filled it up with coal instead of turf! And it was glowing RED! The stink of burning rubber!
