thank you so much for your replies. I am confused (not difficult

) slightly.
The Bagley dish Pamela has linked to looks identical to mine and I also looked at a dish noted as Sowerby 2266 in Carnival glass on another site and that too looks as though it might be identical.
However, what I think I may have noticed is that the star in the centre of the Bagley one on Pamela's site looks different to the centre of the Sowerby one? Is it? the Sowerby carnival one I looked at seems to be more flower shaped/petal shaped, rather than star shaped, kind of elongated points it seemed. My dish has the identical shape in the centre to the one on Pamela's site.
Other than that, mine has a fluted edge in that it goes in and out as the Sowerby one did - does the Bagley also go in and out please?
Thanks for helping. I appreciate it.
