That IS a Baby Rattle… its old silver,or perhaps even pewter at least 47 years old or older… how do I know??? I use to have one of these exactly when I was baby. I remember it cause it was my favorite thing when I was young. given to me from My great - grandma… and later stolen from by a Babysitter when I was 4yrs. It was a bit heavy and the ball piece inside that made the rattle sound could have come out by now.
I’m not real sure about the age cause like I said it was given to me by my great - grandma and it might even be hers… it might even be steal and not Silver at all.
and that’s how they made them back then.
can you imagine how excited I was when I saw it on your site while looking through pictures of silver Rattles in Google?
any chance of you willing to sell it? would love to have it back.
Anyway that’s what it is,
hope that answers your question.
