The Crown Handle Porringer is a reproduction of an 18th century porringer that I believe was made in Boston.
It has a 5.25″ diameter bowl which was referred to as a pint capacity. These were multi-purpose vessels that were used to eat from, to drink from and to use as measures. In fact, if you look at the inventories of 18th century pewterers, they list the porringers by their capacity. The crown, or coronet handle is a wonderful design.
