This chimneypiece was executed with minor alterations to Adam’s design, with oval enclosed rosettes in the capitals rather than urns, the drops in the stiles were hung from bows rather than rosettes, and the frieze was ornamented with alternating trophies and enclosed rosettes. It survived to be photographed by the LCC in 1936, and was sold at auction in the same year.

The design is a close variant of that designed by Adam in 1766 for Lady Shelburne’s bedchamber at Shelburne House (Adam volume 22/113). The Shelburne House chimneypiece design was inscribed by Adam in pencil with the words, 10t House, Back Parlor, corresponding with the intended location of this design, albeit in the Back Parlor rather than the back drawing room. Moreover, this drawing is inscribed with pencil, Mansfield Street, showing that like so many drawings of the 1760s being reused at the Adelphi, it would appear that Adelphi drawings were considered for reuse at Mansfield Street.
