A group of similar dishes engraved with the same arms are known. An example with shaped border, and with the same maker's mark and engraved with the same arms as the present lot was sold Christie's, London, 22 November 1978, lot 177 and illustrated in M. Clayton, Christie's Pictorial History of English and American Silver, Oxford, 1985, p. 69, pl. 6. That example was later sold as part of a pair, Christie's, London, 10 July 1996, lot 183. A closely-related example with maker's mark WW with mullet and pellets below, made in 1673, is part of the Birmingham Civic Plate.
The attribution of this mark is based on research by Dr. David Mitchell for the Goldsmiths' Company.
