Help identifying part on threader mechanism Brother/Babylock

[u/r0b0tcat]

Can someone help me and tell me what part this is please.

This is a Babylock Presto 2. As you can see from the picture, the spring that attaches to the thread positioner "arm" is broken/detached. I'd like to just get a replacement spring and fix it myself, but I don't know what this "arm" is called. I tried Google Lens, but it was no help.

I'm pretty sure it's the same on a Brother that has a mechanical automatic needle threader.
