This is definitely a non-music thread. When I was a lad in South Yorkshire there were many mining villages and communities. Many of my family worked in the pits. I recall miners carrying a metal 'snap tin' to take their sandwiches down to the coal face. This was in the shape of a slice of bread, flat at one end and rounded at the other. Just the right shape for your sarnie. They also carried a water bottle, holding about four pints I believe, to quench their thirst in the hot conditions underground. This was circular with a small spout and a screw cap and was known as a 'Dudley'. I've looked on the internet but can find no explanation for this name, so I thought I'd refer to the fountain of all wisdom and knowledge, Mudcat!!!
Does anyone out there in Mudcat land have an answer for me as to the probable origin of the name? I'd be most grateful.
Regards and thanks in advance.
