Ray, we see the lintel shadow on Frazier in Darnell. It looks nothing like the vertical or off-vertical 'shadow' on Lovelady in either of the Wiegman frames

Agreed, but the shadow on Frazier, I believe, is caused by the left wall of the entrance. The first photo shows a vertical shadow and the second a slightly angled shadow. The reason for the difference in both Darnell photos is that in the second, Frazier is leaning slightly backwards, probably to see better, what was happening further down the street.
