AWESOME!!! Finally, a nod if not absolute proof that these things came in all shapes and sizes. I have several of Neumann'sa books, but none with this illustration. Thank you, my friend!! I'm really attached to these types of specialized naval shot. Yes, I had heard them called 'angels', while the round bar with the flaired ends have another name that slips my mind at the present. Here's one recovered from a military site-
One of this type was on the Pass Cavallo shipwreck in TX and thus, some believe this type of shot was popular with Spahish ships. This opinion was seconded on another site concerning another wreck.
