Hi Annabelle....first welcome to the world of willow collecting! I hope you find it as fun as I have for 25+ years.

I could not get the photos to open, so if you want to email them to me at willowware@aol.com, that would be fine. But, the HA&Co might be H. Aynsley & Co., with most pieces dating from the late 1800s through the early 1930s. They made serving pieces as well as toy tea sets. Send the photos and I will try to help more!
