I want to know the answer to the following question:
Who completed the palaces gilded railing and gates?
All the background I'm provided with is that "Behind the gilded railings and gates which were completed by the Bromsgrove Guild in 1911 and Webb's famous façade, which has been described in a book published by the Royal Collection as looking "like everybody's idea of a palace", is not only a weekday home of the Queen and Prince Philip but also the London residence of the Duke of York and the Earl and Countess of Wessex.". Is that enough to answer the question?
