No luck trying to find information about the Boda numbers on the base of your vase.
I can see why you were thinking of Orrefors.
In the book Scandinavian glass 1930-2000, smoke and ice, they reproduce some photos from a 1937 Orrefors catalogue.
There is a vase with a very similar design by Vike Lindstrand (L 1867) and on another page there is a very similar shaped vase as yours,
( N 1707).
In the past i have written to the Swedish glass museum and they have been very helpful.
I think the figure depicted on your vase may be Salacia, consort of Neptune.
Hope this is of some help.
