Continuity mistake: At the end of the scene where Hyacinth is fighting Major's advances in the greenhouse, she's seen holding fresh flowers. However, just as she's running down the stairs, the flowers are wilted and broken.
Stately Home - S1-E3
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.
Continuity mistake: When the characters arrive at the pub, Richard parks the car not within the parking bay and with a big gap between the front bumper and the bollard. He then goes into the pub. Meanwhile all subsequent shots of the car show it parked right up against the bollard, and in addition a wide shot seen while Hyacinth is waiting for Mrs Fortescue shows the car is parked within the lines.
The Father Christmas Suit - S2-E11
Continuity mistake: In the scene on the way to the church when Liz and Hyacinth nearly crash into the Thorgunburys' car, there are two cars parked in the front garden of the house behind them, a red Peugeot and a white Citroen. At the end of this scene a white Vauxhall Nova has just appeared in the garden.
Continuity mistake: When the milkman picks up the empty bottle, the note is flush with the top of the bottle, but when he stands up it it is sticking halfway out.
A Barbecue at Violet's - S5-E8
Continuity mistake: The BBQ fire is started by the "there'll always be an England" sign resting on the BBQ. When the guests sang that song, Hyacinth is to put the sign down behind the table where the other signs are, not on the grill.
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."
