Holmegaard - Carnaby

I have a yellow, clear cased vase which is the same shape as one from the Holmegaard Carnaby series and I wonder if it is this or a copy?

It is more of sunny, yolk yellow than some of the pictures of the other yellow vases I have seen from this range.
Although it is the right shape, it is 21cm tall and diameter of the base is 7cm. I know the smallest vase in this shape is meant to be 22cm tall and 7.5cm diameter, so mine is just short of these measurments.

It have a smooth polished pontil with gentle ripples to the base.

Could it be the real thing, or a good copy?
Any help would be great.  

Yup, real thing - and one of the earlier colour combinations (opaque yellow cased in clear glass was replaced with opal-white glass cased in transparent yellow a few years into the production run).

There was a bit of room for variation in colour and size, so a few extra mm here or a shade difference there is fine.

Thank you so much for your quick response - very helpful and great to hear it is the real thing!
