In search of matching Teapot

Hello all!

My grandmother gave me 6 cups with saucers, six plates, two small bowls, and a bigger bowl all in the same pattern. She found them at a rummage sale her 55+ community was having. I am in search of the matching Teapot to at least have a way to serve six people tea in matching design. I have tried a few places on the internet but no one seems to have it in stock. Has anyone else taken on this sort of project with any luck or resources to share?

Thanks!
Kayla
