It is known that at least one pedestal for the staircase was executed to this design by Sefferin Nelson, as a single example appears in a Country Life photograph of 1913. Harris has suggested that the design was not sufficiently liked to make three more. The whereabouts of the executed pedestal is unknown, however. It is not clear if it was sold in 1922, as the contents of the staircase are not listed in the sale catalogue, and other pedestals included in the catalogue do not appear to be related to this design.

At present there are four similar pedestals in the library at Kenwood which are on loan from the V&A Museum.
