One of the things that Mum has kept for years is this rattle. Thanks to the Internet, I discovered that it was made in Birmingham in 1921 by the firm of Crisford and Norris. The handle is mother of pearl and the figure is made of sterling silver (it has a hallmark). A teething ring would have gone through the loop on the top. It’s a curious item.
I found this photo of one in mint condition.
