I have here a 21cm. dish and two nappy dishes of 12 and 13cm. all with the same pattern. The nappy shown separately is the 13cm. one and appears to be a footed version of one, no. 18475, shown on page 9 of the pre 1958 Hermanova catalogue from Marcus Newhall's CD. I can't find the other two but think they too may be Hermanova.
