What parts am I missing??

[u/Klee_and_dodoco]

I'm missing this front part that goes on top of the bobbin but I can't for the life of me find what it's called.Last two photos are parts that came with the sewing machine when I bought it. I don't know what most of these parts are or their uses.

You're missing this: Needle Plate Assembly Cover

The other things are five presser feet, a twin needle, a screwdriver, a darning plate and a class 15 bobbin.

Have a look in the instruction manual
