Radcliffe Colliery

[Coquet]

Here is a mid Victorian engraving of Radcliffe Colliery. From an original colliery invoice. I wondered how stylised this is, after seeing the unlikely winding equipment on the left. But....after investigating this I think the structure on the left is a counterbalance affair to the main winding equipment. this was generally some heavy chain attached to a winding rope connecting to the main winding drum. this 'weight chain' had its own shaft which it dropped down during winding operations. I have a picture of Wearmouth Colliery with the same type of affair which was built in 1848 - close enough to the date of Radcliffe to be using similar equipment?
Interesting anyway. Warkworth Castle also on the right?
