I found these today.
I hope the pictures are enough.
The one that is oval shaped is lead and has a center s shaped piece.
The other one that is shaped like a musical note is a heavy disc attached to a rod that is not broke off. It is actually rounded on the one end.
Any ideas on either one.
I've only found one hem weight.
A site which began slowly in 1958 and began to get heavier use from the early 1960 's on.
I was happy to finally identify it as a hem weight. I took it to a woman friend who enjoys metal detecting, but also knows a lot about sewing.
I thought she would be impressed with this old hem weight I had found.
She opened a drawer on her old sewing machine and showed me an old open package just like mine and said that she did occasionally use one now and then when fixing curtains.
So I have a rough time frame leading right up to today, 2018, ... because she's still sewing things.
