Help to identify this OWL please

Can anyone help please in identifying the Owl and the pottery mark that looks like a raised pottery diamond. There are no numbers, writing, mark on any other part of the owl. The owl appears to be hand painted. Thanks.

 

Hi and WELCOME to Antiquers, Harry!! That's a pretty Owl!! There looks like there might be something where I've circled.....if you can get a better shot WITHOUT flash, or whatever giving reflection, I MIGHT be able to pick it up....OR not....some of us can try to enhance images..... sometimes with success and sometimes without!!!! But, we TRY!!

 

Fred the owl...?

 

Welcome to Antiquers Harry!

 

Thank you all for the welcome, I have taken a very close look and there are no other markings, marks in the glaze showing up in the pictures.
However I will take some more pictures.

Thanks.

 

It has the shape of a British registration diamond however I'm not convinced that's what it is.

Awhile back I recall a pottery mark that was shaped like the country it came from or a province in that country. I'm wondering if that outer line is what that is. Can't remember what country that turned out to be though. I'm thinking is was an island nation like Japan or Taiwan.

EXAMPLE:

 

The other marks are just runs in the clear glaze.
I did hope someone may recognize the owl, I cant see that it was the only one made but I have failed to find another on the internet.
Thanks

 

I did find what I think I was remembering about the mark discussed. It's not your mark but I do think your owl possibly might be Chinese or Asian.

Is that a capital letter I in the center?
