A hasty post as I found my negatives file and started scanning. I'll post more detailed descriptions later. the photos were taken during 1981 when I visited Sutton Manor (then all steam worked), Bickershaw, and Parsonage Pits all in Lancashire where I was living. yes -I'll upload the Bickershaw and Parsonage photos when I get a minute. Sorry - no underground shots though! Hope you enjoy the engines.
The map is the territory - especially in chain scale.
