The wage records for that month include the entry for ‘M Deviea’, deemed a phonetic spelling for Monsieur Duvivier.
At this time, the Chamberlains were known to be decorating Caughley blanks. However, this is the only service of this kind and it appears that Duvivier left Worcester before it was completed. Some of the surviving pieces from the set seem to be by another hand.
Geoffrey Godden wrote about the service in Chamberlain-Worcester Porcelain and this jug, which comes for sale at Bearnes Hampton & Littlewood in Exeter on July 21-22, has two paper labels for the Godden Reference Collection. Estimate £1800-2200.
BHL sold a similar trio decorated with children at play from the same service in April 2019 for £3100.
