Topic: olive and blue water set.

[Paul S.]

I thought I remembered that this colour combination was something important - but have a feeling what I'd had in mind was the Sowerby 'Venetian' series - but that only has blue trailing anyway.
So I've no idea about this pair  -  assume water jug and tumbler - high quality ground/polished pontil depression on both, and the sort of wear that might mean reasonable age.           The jug is 6" tall (155mm).
All thoughts received gratefully, and thanks for looking
