@sallyhinch point. @dougal I will take all those under consideration!
@Iwrats just a slowish cowp while dithering about where I was supposed to turn. Brakes on, back wheel went sideways, and then it seemed best to let gravity have her way. A nice young lady stopped her car to check if I was / wasn't damaged and I was an undignified and muddy workshop attendee afterwards so the primary injury was to any lingering sense of professionalism...
