The photo supposedly showing the shirt factory was taken at the “back” of Shiney Row. Between the bottom and Shiney Row and the gasometer was the surface infrastructure of the Doctor Pit – rail sidings, timber yard, workshops, heapstead, offices etc. What is shown as the Shirt Factory was one of the Dr Pit offices, probably the Planned Maintenance office.
The shirt factory was at the top end of Bedlington roughly where the library is now. There used to be a footpath from Shiney Row to the front street, exiting near the Bluebell pub. The entrance to the shirt factory was from this footpath.
My photo was taken from Glebe Road looking toward the Dr Pit.
