... and can take a quick photo for me?
It's the overedge C foot. I've just broken a needle on mine, it hit the little wire thing underneath the foot. I can't for the life of me remember if the two prongy bits under the foot are supposed to be two prongy bits, or whether they're supposed to be joined in a loop at the top. Has my needle knocked the top off it?
I've googled but can only see pictures from the top - if anyone has one handy, could you take a photo of the bottom for me? 🙏
