I hope it's ok to mention this on here as afaik such analogue meters are well past their sell by date.

I remember someone at work saying they knew someone who had done this and had left the meter running backwards for too long. They then had to leave several electric fires on to get the meter back past the starting point at which it was last read. I thought this was just a story at the time but 30 years later it now seems it may have been true.
