I think if you check your bottle you will find out that it is a Glendullan 12. I have polished off the better part of two bottles. There is a European release and an Asian release. Someone correct me if I'm wrong but my memory is that the Euro folk get MacDuff and Asia folk get Ord.
Previously (back in the 1990s), The Singleton had been Auchroisk 10 yo vintage bottlings.
