Hi and welcome
- sorry you had so much trouble registering.
I can't help with your bowl I'm afraid, Orrefors is not my area.
Have you tried searching simply for enamelled or painted Orrefors?
"Values" of items in the secondary market are highly subjective; we don't really tend to discuss them here.
Something is worth what somebody else is willing to pay for it, in that place, at that time.
Ball park figures can be obtained by finding similar items on finished auctions, then dropping the figure a bit because at least one contender, the buyer, is now out of the running.
