What is this threaded terminal called?

[Sneaky Duck]

I just bought a boat that has the forestay connected with this threaded piece. I've never seen one like this before, and while I have 2 forestays with the boat I want to know what it is so that I can buy some spares. Or at least know where to find them if I need them. When I google threaded forestay or shroud terminal all i get is turnbuckles. Any idea what it's called so I know what to search for?

The single shank swage ball is easy enough.

This is the other end. The threaded section from the forestay threads into this piece and a cotter pin goes through the hole and keeps it from backing out. Pretty simple setup. It's very small which is important because the forestay is adjustable but the range of adjustment isn't big enough to fit a more bulky fitting below the deck. I looked it over and there are no markings on it anywhere.

I think your first picture is what is called a swage ball swivel sleeve (found on lexco cable):

The second piece I'm not sure where you'd find it.

I'm thinking custom-built. Seems like Star guys would do that sort of thing. I've never seen anything close to that piece and looked just now with pretty good Google skills. Maybe an aircraft part though.

While not identical, blue wave marine have some very similar style fittings for terminating fibre stays https://bluewave.dk/products/rope-fork-stainless-steel/
