2147 Medium Speckled Swan may not be made by Crown Lynn

Very happy to hear that Crown Lynn used a speckled glaze sourced from ironsand from Bethell's Beach.
However according to Ernie Cooper that was in the 1960's and the medium swans were made c1981. So this has put doubt in my mind, so I asked Tom Clark Jnr about it and he didn't know of any swans that were glazed with a speckle glaze.
The lustred swans with gold beaks were not made by Crown Lynn according to Bruce Yallop and I've seen at least 8 of those. De' Arn come to mind as they did use lustre and gold on their work.
I've seen at least 10 of these speckle glazed medium swans.
The medium swan master mould was never used by Studio Ceramics, they made one of their own. Perhaps that master mould was used to make these 'Replicas'?? Make me feel unwell
More research to do obviously
