A couple of months ago I bought an older serger at an estate sale. There were several other machines there that I didn't buy, but the woman gave me a bag containing a pile of "mystery feet". Can anyone help identify these? Wondering if they are worth keeping or not. In some of the photos they may look rusted, but they're not - just a reflection.
