The chest is possibly by Thomas Chippendale and stands on horizontally blocked brackets – a feature of much of Chippendale’s cabinetry. Further reading on horizontally stacked corner blocks and associated problems here, here, here and here.
Three of the chest’s four feet are missing one or more strata from the bottom of their horizontal corner blocks (figs. 2 & 3).
In their accompanying footnotes, Bonhams mention a related chest, lot 32, sold by them on the 13th of June 2012 in their Fine Furniture and Works of Art sale in New Bond Street, London, but for some reason say nothing of another, virtually identical chest, lot 138, offered by them in their Home & Interiors sale in Edinburgh on the 24th of February 2016.
