I would like to take the opportunity to thank those on the list for the help that you all gave me re; Horse whims or engines etc. I will be visiting the coal authority in due course its only 20 miles from me, also I would like to say to john that my granddad worked in Hatfield Main and I grew up under its front door, in Stainforth. Just as an after thought in 1838 two miners lost their lives on the whim, as they lashed them selves to the chains that hauled them up out of the mines, but it didn't stop quick enough, the report says that there was a 14 year old boy in charge of the engine. Regards to all Bryan Maloney.
