NER class G6 x2 on SLS visit 18 9 1921

This photograph comes from a collection of postcard-style prints, collected by W.Beckerlegge and acquired by my father. There are two main sources of these commercial photos, produced around the 1923 grouping, W.H.Whitworth (WHW) and the Locomotive Publishing Company (LPC). The photographers have not been credited on the prints, so cannot be recorded here.
