Hello
I purchased 2 large bags of vintage looking notions and trims and sewing accessories, and these things were in the mix!
I am still fairly new to sewing, and no little to nothing about the older machine parts.
Can you help me figure out what this stuff is?
The black metal pc I was able to identify by a readable part number. It appears to be a Singer needle threader, but not sure for what models.
The needle has a small and also a large eye and a blunted end.
I can SORTA make out that this small zipper foot is Singer, but can't make out the part number and don't know if it is maybe missing something.
That other metal pc only has Japan stamped on it, but nothing else.
And here's where I'm sure I sound like a newbie

, those 2 small rocks look like they were for sharpening something I can see the wear, but what would they have been used for?
Do any of you experts recognize this stuff? I truly appreciate your input!
