Hi Class31, thanks for raising this; we've made an adjustment to the NGR field for this image. The use of NGRs is the key feature that all three archive partners have in common for cataloguing air photographs - but we have slightly different rules about how to determine and apply them. This is for historical reasons (each starting to take, collect and catalogue national collections at different times and into different systems).



Yours, Katy

The steelworks was briefly reopened in 1915 to aid in the production of materials for World War I and works closed for the last time in 1919.
