This picture looks like it was taken from an aeroplane flying to the north of the site, probably in the late 1930s. I wonder how realistic this picture is of the Billingham site, although it does show in the far distance the Newport Bridge?
I understand that Ordnance Survey maps did not show the location of the plant, as it was built before WWII to produce high octane petrol for aircraft engines. It is also interesting that the actual coal hydrogenation units are not marked. Were they under the arch-like building at the lower centre of the picture?
