Hello Rose, being new to this site I'm enjoying looking through the old posts, and I hope that the little knowledge I have can help solve some old mysteries, such as this one!
I used to have a very similar sugar bowl and cream jug in the identical colourway. Neither were marked by the maker but one had the original label on. They were from a Canadian pottery but for the life of me I cannot remember the name. I think that it was something like 'Valaris' or 'Valarus' but don't quote me on that. I'll dig through my older files when I get a chance, hopefully I will have listed them somewhere.
