I am pretty confident that the bottle you are looking for is listed in our database.
My best guess is that only its series is not set to “Sherry Oak”.
By any chance do you mean this bottle https://www.whiskystats.net/whiskydetail/?whisky_id=2228
(note that you find pictures of the bottles when you click on one of the “Latest Observations” at the bottom)?
