Early Georgian sterling tankard John and William Deane, London 1763 with American historical significance

A substantial early Georgian sterling tankard made by the London partnership of John and William Deane in 1763. The handle has a lovely heart at the bottom. The front is engraved with the initials JMMc and also with the name Anna Mitchell McCallister April 1879. Anna McCallister (1849-1922) was a physician in Philadelphia, and on of the early graduates of the Womens Medical College of Philadelphia. Her grandfather, John McCallister, came to Philadelphia from Scotland and established The McCallister Company, which dealt in spectacles, canes and whips and became the dominant retailer of optical equipment in Philadelphia during the mid 1800s, run with his son John McCallister, Jr. Based on the monogram, it is likely a gift from Anna's father or grandfather, possibly on her 30th birthday.

Condition: there are a few dents on the body of the tankard, but there are no repairs, the lid is solid and the makers marks are crisp and clear. More photos can be provided.
