G'day Julie,
Glen will be in later to set us all straight, but just for the moment,
1. and 2. are "LILY" vases, which were made in 3 sizes: L/"lily" was 9", S/"lily" was 7", Posy Set was 5". Flint, blue green and amber. (According to Glen's CD, they first seem to appear in the mid 1930s, and were made well into the 1950s)
3. Hmm. You're right, I can't find it in either what I have on Sowerby or Bagley.
Will have to wait for the experts.
