the one I have personally used was a limited edition: 1987 QC of only around 1300 bottles and it was an OB.
This particular one comes not in a cardboard box, but in what can only be described as a real straw condom
I have since seen another listed in a different online shop, but it was in a typical Glenfarclas cardboard box and I can't remember if it was also 1987 and limited.
The Glenfarclas QC, unlike the Laphroaig WC, is entirely matured in a QC and not just finished in one.
The correct price to pay would be €60 to €65 which would equate to 40 GBP to 44 GBP.
Let me know if you don't find one, maybe I can help.
