Woodbridge Antiques has dated this piece to the 1920s.
The reverse of the handle is the mirror (there are some marks visible to the glass, however, it is still very usable and we mention these for accuracy). A number has been engraved on the mirror side of the handle: '792K'. The silver is in super antique collector's condition.

A superb item for a collector of Art Deco silver, with clear hallmarks on one side for the Birmingham Assay Office with a date mark for 1928, and Lion Passant indicating the finest sterling silver. (The silver maker's mark is slightly rubbed.)
