The pictures don’t show a u-shaped clip. Just playing devils advocate, errrr, mouth-breather at the insurance company looking at the picture, so again, without further evidence, it would be a toe-nail, or possibly, other.
Man, are you thick. Of course a photo of the other side is needed for verification. I took this photo a couple of years ago, and thought it was a simple angle bracket, as you do now. Go back to the original question I asked…Does a U clip with 2 nails on EACH side count as a clip? (assuming full verification). This clip is the same basic design as a H10, only made 55 years ago, sooooo, it probably won’t look exactly like a H10.
