Duke of Wellington Parian Bas-Relief Portrait Plaque Brooch, After William Boyton Kirk RHA, for W. H. Kerr & Co. Circa 1852.
Approximate weight is 19 grams.
Approximate dimensions are 5.8 cm height and 5 cm width.
In good condition with no damage to the portrait plaque. A cabinet piece rather than a wearable brooch as the pin does not lock shut fully. Possibly later converted to a brooch.
