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.
The Father Christmas Suit - S2-E11
Revealing mistake: There are many Christmas cards scattered around the house but you can see in a lot of the shots that they have nothing written in them.
Visible crew/equipment: When Elizabeth drives off, after Hyacinth has 'visited' Daisy, a cameraman's face is visible in the rear window of the car.
Visible crew/equipment: When Hyacinth gets back in the car after 'visiting' daisy and Elizabeth drives off, a cameraman's face is reflected in the rear window of the car.
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.
Visible crew/equipment: The boom mic dips in shot at the top right corner when Hyacinth says she will make tea. (00:01:33)
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."
