I would have said they are not top quality, Christine. They are quite sturdy although fine, and there are a couple of little areas underneath where the glaze is just a tiny bit rough. I would guess 40's is about right Lynne, as they came from an old friend of my mother's.
I must admit, the kt confused me, and I would have thought they were continental if not for the 'Made in England'!
Here's a closer pic of the pattern. The pink glaze is sort of iridescent, which I found hard to capture in a photograph.
