Many thanks Jan for your time and interest looking at my vase. I think your explanation is probably correct when you show the 25/9 the right way up and note the clay is not white,  that it is not De Delftse Pauw. Which makes it all the more intriguing. Perhaps it is a British copy! I will do some more research here.

Best regards

Thank you Patrick,that is really useful as I was unable to find maker in my own internet searches.

Interesting to see the factory's demise was only last last year!
