A pair of mirrors (Adam volume 20/8) but not the girandoles (Adam volume 20/9) were executed by James Gravenor who had been responsible for the Corinthian capitals in the door frames and Venetian window. Harris suggests that the girandoles were abandoned as, owing to their size, they would have detracted from the paintings on the wall. A very similar design to Adam volume 20/8 was made for the Duke of Manchester for Kimbolton Castle, but executed with alterations. There is a duplicate of the mirror design in the drawings collection at Kedleston.
