The mark is for 1890 - 1910 according to this site.

The registration number dates the design to > 1904
I had found the first link but the second, with the date...
Thank you for going to so much trouble. It's really nice to know the age of something.
I think this would be called a 'Carlton' design. I have found plenty of Shelley Jelly moulds but none are mentioned to have the mark of Wileman & Co. I have also seen a few similar to yours with the mould only on the inside, those ones date to the 19th century but I found no Shelley ones like this.

Millers says that the deep indentation on the top surface is an area for the cream to be poured over the top.
I'm curious, or , more likely thick
And have never, ever made a jelly.
What do you think Millers mean by that? Don't you just turn said jelly out of the mould and slosh the cream over it ?
If you ever find out anything about the outer surface, I'd really appreciate it.
