Singer sewing machine (Kingsclere RG20)

On offer is a used Singer Favourite Sewing Machine.
Electrically it works, but, I have never used it to sew with as it does not have any accessories, eg the shoe (I think that's what it is called) that presses down onto the material as the needle comes through it.
 As the machine runs, it does have a very slight knock, but, maybe a good service inside will cure that.
Also on the top it looks like there might be something missing, but, I wouldn't know (see close up photo).
Anyway, hope someone can use it. I got it off Freegle a few years ago for a project to mechanise a cheap knitting machine but never used it.
What you see in the photos is what you get - there is nothing else to go with it.
Collection is from Kingsclere.
