This item is a vintage pewter triangle nappy bowl (model number 2162), manufactured by the Preisner Pewter Company.
Key Characteristics
Form: Features a distinct three-sided (tricorn or triangle) tricorn shape with a shallow basin and a single looped strap handle.
Function: Traditionally used as a "nappy" bowl, which is a small, shallow serving dish equipped with a handle, ideal for passing around finger foods, nuts, mints, or small candies. It is also frequently identified as a porridge bowl or porringer due to its single flat-loop handle design.
Material: Made of solid pewter, giving it a dull, classic silver satin luster that naturally develops a deep tarnish and patina over time if left unpolished.
