This picture is looking up river from the Victoria Bridge. I think that the bridge in the distance is the new A66 bypass around South Stockton. All the industrial buildings and warehouses on either side of the river have been replaced. The brick building on the right has a sign which seems to say WLFURN Engineering. The one on the left, close to the road bridge also has a sign, but I cannot make this out. However, judging by the funny chimneys on the crown of the roof, it looks like it was doing metal work. Hot forging or casting?
