Made by Thomas Meeson and Abel Grove of Birmingham c1815-20 their hallmarks to right of handle, and maker's label with secondary marks inside the base. Possibly uniquely, this is an example of a pre-Imperial half-pint mug being extended to Imperial capacity by the addition of a very well executed rim extension, which included the repositioning of the handle to a higher place on the body. Provenance: formerly in the collection of the late Michael Boorer his label 14/95 (signifying this was his 14th purchase in 1995) under the base (Lot 11 Bonhams 22.11.2012). Verified to upper centre of body with a partially legible double struck verification mark, which looks to be DERBY below a crown. Capacity is now 10 fl oz, but originally would have been a wine half-pint (OEWS). 4⅛" tall with 3" base diameter. 287g weight. REF: C3467
