The piece in the link below looks very similar to yours, but height is 25.5cm and weight 1.517kg. I don't know how much these pieces would vary. It is also unlabelled, and does not give any reference for the attribution.
You haven't mentioned why the date of 1963 was indicated. The wear is. It what I would expect to see, but it could perhaps have been in a cabinet for years. There are a lot of murano style vases coming from China, which can make it more challenging to identify pieces. With any luck, someone on the board will have a labelled one in their collection.
