Based on the maker mark "Spencer London" and the distinctive British hallmarks, this top bar dates to the early 20th century (typically between 1900 and 1935).The exact year is determined by the stylized letter "V" stamped inside the shield cartouche:If assayed in London (indicated by a leopard's head mark), a stylized "V" denotes 1915.If assayed in Birmingham (indicated by an anchor mark), a lowercase "v" denotes 1920.
