via Trade Gazette, 04 Feb 2019: There seems to be no mention of how the bronze bell was acquired from Battambang.
A large bronze Cambodian ceremonial bell from the south-east Asian Bronze Age was the top-seller at the Peter Petrou: Tales of the Unexpected auction at Christie’s last week.
Made in the Battambang province sometime between the 2nd century BC and 2nd century AD, the 23in (58cm) high bell features overall decoration with geometric scrolls in low relief.
It was knocked down for £100,000 against a £40,000 high estimate.
