I introduced the John Bassett Porringer several years ago. John Bassett was active in New York City circa 1720 – 1761, and surviving examples of his work today are very rare. His sons Francis and Frederick were also skilled pewterers who produced excellent wares.
This Bassett Porringer has a 5.25″ (pint) bowl with two incised lines on the rim and an “Old English” type handle. Another classic style.
