The quality of the casting is quite detailed, crisp, all intact. Gilding on the obverse is largely intact. Patina is beautiful. Object measures 19cm/7.5" in diameter.
This piece possibly functioned in a cover for heat or ventilation duct, or had another function in a luxury cabin on a Carron Steamship Line ship. Based on the subject matter and the decorative elements, I would date this to the late 19th-early 20th centuries.
