In the Blyth book you mention with the school children on the front, if you turn to page 87, the top picture is of the Tug Spout and the High Quay. The Lord Nelson is out of shot to the right, but it gives you an overall impression of what the street was like circa 1925 from the opposite side of the river. I think the other picture and mention of the Lord Nelson, is the picture of the Tug Spout on page 18.
