A colleague is researching the history of some old coal mines in the village of Dore, in south-west Sheffield, but there appear to be no photographs extant.

I'd be grateful if anyone could steer us in the direction of any photographs (preferably on the Internet, otherwise in published material) which show the typical surface and underground aspects of very small, narrow-seam mines, especially if worked from around the turn of the 19th-20th century up to the start of the second war. If these were of mines in South Yorkshire or North Derbyshire, so much the better. To illustrate a bit more history, photo's of bell-pit workings would also be welcome.

The purpose is to be able to illustrate how the Dore mines - of which practically nothing remains - might have looked. They were small enterprises, not particularly deep, and would have had only a few employees.
