Continuity mistake: When the inside of Onslows and Daisy's house is shown there is no second door in the hallway right inside the front door. When the angry woman storms in to the house from the outside, there is a second door that she goes through after the front door. You can it because the light changes as if a door is being opened and then closed, much like a swinging door.
Answer: I have asked myself the same question for a long time. It is Rosina-Queen's fine bone china, pattern "Olde England." It's the china that appears most of the time in the series. The Royal Worchester double-glazed Avignon (for candle light suppers) is really Royal Doulton Avignon, pattern "The Moselle Collection." And the Royal Doulton with the hand painted periwinkles is in reality of course Royal Doulton Colclough, pattern "Braganza."
