The auction on February 2 comprised mixed pieces from Mr Fisher's Camberwell home and stock from his Pimlico Road gallery, from which he is moving to new premises.
The sale had been estimated to fetch £1.4m-2.4m, but with plenty of the pieces that made up the distinctive Jamb look contested well past expectations by multiple bids, the all-day event ended up totalling £3.15m hammer.

Chimmeypieces are a Jamb speciality and the day's top lot was the 7ft 10in (2.4m) wide, mid-18th century example pictured here, in verde antico and statuary marble, made to a Palladian-inspired design by Isaac Ware.

It was possibly carved in the workshop of James Richards and fetched £150,000, plus premium.
