I have been given a great advance birthday present - a Fujifilm Finepix HS10 with a 30x zoom.
The statues at the base of the cupola are made of Gibbs & Canning's white faience, so it is probable they were created by the company's chief modeller John Evans.
The one on the left holds a cornucopia o'erflowing with fruit'n'veg, and points upward to the prima ballerina. The one on the right brandishes a palm in her right hand and holds a lute rather awkwardly with her left, strumming with her thumb.
