This wonderful and very hard to find Kerr buckle features a mermaid and lobster. The brooch measures 3 1/2 inches (on a curve) by 2 7/8ths inches. The marks are faint and are sterling, the Kerr mark and what looks to be the number 1145 (possibly 1143). Condition is very good with light surface wear. This buckle can be worn on belting and could also be easily converted into a brooch.
