The example below, measuring just shy of 6ft (1.82m) wide, was sold on March 30 by Hartley's (15% buyer's premium)of Ilkley.
Geographically close to Thompson's Kilburn workshop these auctioneers have a strong following for Yorkshire oak and had been a little disappointed to see this pre-War piece sell at the lower end of a £4000-6000 estimate.
The sideboard was offered by Moore Allen & Innocent (15% buyer's premium) in Cirencester on May 27.
It shares many of the same features including the distinctive nine drawer arrangement, wrought iron latch and hinges and the darkening patina of a 1930s piece. However it was deemed a better example on account of its carved backboard, the canted corners with carved trademark and its waisted octagonal feet - factors that saw it bring a more substantial £7600.
