Alignment mark

Alignment mark
United Kingdom (GB)
Used when processing the map images to align different layers at the edges but usually removed from the final product.

Usually when I find one there are more arond along the edge of whatever layer was being processed.

There is another more elaborate mark to the south. There may be more around straight to N,E,S or W.
