Looks as though it should be, but haven't seen it my books. Held up to a good light, it is quite a stunning green. Base has a ground flat outer rim, with fair amount of wear, and some small chips on the edges, unfortunately, so had a fairly hard life. Inside there remains some water staining at the threequarter height level, so maybe some reasonable age.
6 inches/150mm tall, and top is simply moulded/fire polished. Vases are possibly the most difficult things to id - so many millions of them, but this seems distinctive - so hoping someone may recognize the design. Thanks for looking. Paul S.
