Estate Weathervanes are considerably larger then the Standard size weathervanes. Call or email store for measurements. You can let them weather and they will turn a dark brown and in time they will patina to a greenish color. You can speed up the patina finish by misting salt and vinegar in warm water on them or you can keep them shiny by spraying them with a lacquer spray called Incralac Lacquer Spray.
