The arms are those of Pindar, for Sir Peter Pindar 1st Bt. (d.1693), of Edenshaw, sometimes Idinshaw, co. Chester, Collector of Customs in Chester, who was created a baronet in 1662. The title became extinct on the death of the third baronet of Nerquis Hall, co. Flint who died circa 1705.
In Silversmiths in Elizabethan and Stuart London, Their Lives and Their Marks (London, 2017), in which the present lot is illustrated, David Mitchell suggests that this mark is probably that of Marlyn or Martin Gale (d. after 1682), who joined the guild in 1661.
