Help with identifying a blue pitcher with pewter (i think)lid

by Kaye Malloch
(New Zealand )

I have not been able to find out any information on a beautiful pitcher I have inherited. The name on the bottom is Eureka done in gold with a signature of some kind underneath it and a number stamp 262788

It is a beautiful cobalt blue with gold leaf trees on it and raised embossed blue and gold on the front and back. It is stunning and in perfect condition. I have no idea of date or who the pottery factory was. It is possible it dates back to early 1800s or earlier as it came from my great great grandmother.

Can anyone help.

Thank you
