Visiting the Royal Norfolk Show, I came across this metal cage which looked quite interesting. I didn’t know exactly what it was, but took a few photos anyway. I now know it is a Cattle Crush, which secures the animal whilst it is being examined or treated. This model is the Tamar Squeeze, manufactured by L.M. Bateman at Cheddleton, Staffs. There were some side panels which I have cut away, and duplicated a couple of wheels, which I tacked on also. I put the ‘Lock’ and ‘Unlock’ labels on the frame too, hence the title. Looking for a background to set the frame against, was a long process. Eventually I selected a cropped shot of a jetty in Queensland somewhere. I applied a filter to give it a gritty effect, and darkened it a bit to give some contrast for the main image.
