A very similar belt hook, of nearly identical design, execution and proportions, dated 18th century, is in the collection of The Metropolitan Museum of Art, accession number 02.18.374. |The mark on the magnifying glass likely refers to Bensabbot of Chicago, a jeweler founded in 1878 who, like Edward Farmer of New York, was known for mounting Chinese jade and hardstone carvings in precious metal housings to re-purpose them for the American luxury goods market.
