Wonderful Walker commemorated by a sundial

The curate of Seathwaite in the Duddon the 18th Century, immortalised as Wonderful Walker by William Wordsworth, is commemorated with this sundial by the church door. It is stuck on to a stone he allegedly used for shearing sheep, a job he did to bolster his stipend. It's a very physics thing, I think, to have a memorial sundial. We called by at nearly noon BST. That means 11am GMT, and it is the latter that is shown by the sundial. The door of the church is on the south side. As you go in, the sanctuary is on your right, the east side, the direction of the Holy Land. So I can tell that the sundial is correctly aligned.
