The arms are those of Menteath, Kerse, Co. Stirling.
These wine coolers are a variation upon one of the most well known Regency silver designs. Of fluted bombé form and applied with oak leaves and acorns, the design is attributed to Edward Hodges Bailey, who worked for the Royal goldsmiths, Rundell Bridge and Rundell. A drawing for a soup tureen from Rundell's design book is in the Victoria and Albert Museum.
This pattern is most commonly associated with Harriot Mellon, Duchess of St. Albans, the actress and wife of banker Thomas Coutts who amassed one of the largest silver collections of the Regency era. Two soup tureens from the St. Albans service are illustrated in The Lillian and Morrie Moss Collection of Paul Storr Silver, 1972, p. 132, pl. 68.
