So were all the pieces for the Perth Wedding gift specials as regards shape and size and colourway?
As the vase is not shown in the boardroom picture and considering the above is this vase somewhat unique?
The answer to your question is no, the colour scheme was first used in 1947 for the wedding gift but was used right up to 1961 in a wide selection of bowls and vases of different shapes and sizes.
The Wedding Gift set was a table set for drinking and eating from, so I would discount the vase being part of the set IMHO.
