Quite a contrast (technologically speaking) between the earlier 1930s operations and the later, post-war processes. (Still bloody hard work, though....)
I liked the swivel-couplers on the mining skips as they were inverted and unloaded, and yet remained coupled together.
Another couple of winners, Fred!
