You are right to wonder about the age of this decanter given the whittle marks and the applied lip. The maker definitely went to the trouble of displaying a hand-blown look and feel.
I contacted a Danish friend of mine (also a bottle collector) who has one. He reports this was made by Holmegaard of Denmark in the 1970s. He says there is an amber example on eBay right now.
