A watercolour showing a detailed view of a barometrical clock, after RCIN 2752. The rosewood case of the clock driven barograph is shown crowned with a gilt orb, flaked by the figures of an elderly man and a putto. The case is shown decorated with gilt bronze ornaments and is supported by a wooden base. A loose plan is shown in pencil to the lower right and measurements are shown along the right side of the case. A single pen and ink line border is shown around the edge of the sheet. The Pictorial Inventory consists of three volumes containing a total of 230 drawings. It was originally created as a pictorial record of the clocks, vases, candelabra and other miscellaneous items from Carlton House, as well as selected items from the stores at Buckingham House, Brighton Pavilion, Hampton Court and Kensington Palace to be considered for use in the refurbishment of Windsor Castle. Artists from an architectural drawing school run by Augustus Charles Pugin were employed by George IV’s supplier of furniture, Nicholas Morel, for this epic task. After Morel had finished using the drawings as an aid in creating his furniture schemes for Windsor Castle, the drawings were bound into three volumes and delivered to the King’s Inventory Clark, Benjamin Jutsham, where they assumed the role of an inventory. At some point in the nineteenth century, further drawings were added to the original 214 supplied by Morel. Many of the 230 drawings have been annotated by Jutsham or by a later hand and many inscriptions, including some signatures, have been erased.
