"Whitworth" wrench sizes. Also known as British Standard, and of course labelled B.S.on the side of the socket, at least in American brands like Proto.
I still have a couple of these sockets that I got for a '53 BSA motorcycle I had 40 years ago. I think most of its fasteners accepted S.A.E. tools properly but there was one size slightly larger than 9/16 and another about 7/16 that required the Whitworth sockets.
Was it Early Ford that used those odd 1/32 graduated wrench sizes? I still have a thin 19/32 open-end and something makes me think I got it for late flatheat tappets.
