Anyone recognise this concealed cistern?

There's water spraying out of the top of the filler, and it looks like I have to remove the cistern to replace it then it would be as easy to replace the complete thing.

Anyone know the maker?

No, but if you need to replace I have these and find them excellent: https://www.wolseley.co.uk/product/grohe-adagio-37...
