The mask and casts were originally estimated to fetch between 1,500 — 2,000 pounds ($1,900-$2,500) at auction.
As the magazine Antique Collection informs, the previous owner found them among the belongings of his grandfather, who was a merchant marine sailor. It was difficult for the auction staff to evaluate this lot.
"It was difficult to give a saleroom valuation, but an identical mask and hands were sold in 2012 for £3,600, so we decided to offer it with an estimate of £1,500-2,000," the magazine quoted Dan Ponder, an employee of the auction house.
It was reported that a bronze mask and hands in early August were acquired by a foreign collector by phone.
