A Four Ton Crane

If vintage cranes aren't your thing, my apologies. They weren't my thing until last week. Now I find myself immersed in the history of my beloved Caledonian Canal and it's cranes. This one was constructed by Butters Brothers of Glasgow, (see extra). No date is given, alas, but the plaque says its a '4 Ton' crane. It's a rather complicated beast, as you can see. Tomorrow I will show you some interesting canal related housing.
