Casting is quite detailed and crisp. Gilding 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 in a Carron Steamship Line ship. Based on the subject matter, composition and form I would date this to the first third of the 20th century, modeled in a very nicely-executed Art Deco manner.
