Following Andy's tip-off that the Northern Mill Engine Society were having an open weekend, I headed for Bolton. The museum is located in an old cotton store adjacent to the former Atlas Mills site. The place is stuffed full of preserved steam goodness and various ancillary bits. There was lots running and everyone was really helpful and keen to let people take photos of anything and everything.
A selection of images from the day. I think I got a bit carried away with the detail shots, especially on the Diamond Ropeworks engine.
