Hello again Dipper thanks for posting those. It's a nice dyke that. Seems quite well built (from what I can see) and semi coursed,with a good even level on the copes too,which is kind of what you expect for dykes that are property boundaries.
There is a running joint in the section pictured,but a few of those over a hundred plus metres is to be expected.
Looks like most of the stone is still there in the failed sections. Digging about will retrieve some also,but they might need supplemented. Maybe somebody local has a pile of 'waste' stone.....
