Tea strainer

This tea strainer is absolutely cute and very elegant. The idea is that you tip it sideways to strain your tea and then return to an upright position to allow any drips to fall into the facetted glass bowl thus preventing stains on your hostess' Battenberg lace cloth.
The clever bowl design of the neck being smaller than the bowl contains any previous drips when using again.
Now I know these exist I'll start a little collection for some very elegant high teas.
Some huge eye rolls and sighs from partner at this point.
No discernable marks so I presume its EPNS and Edwardian rather than Victorian.
