because I insisted on including the complete thing (including the thing above the window the name of which I can't recall), it means I haven't got the better image which I first saw - I could crop it down, but the lighting is wrong
@selkie@jodies@narayani@kipper1951 thank you for seeing it better than I did - and making me Popular! [PS: 3 on the Popular Page at the same time - wowzer!!!]
It's always hard to know what to include and what to leave out. The lintel over the window is a lovely example of how this was done before the advent of concrete, and better for it.
