I have in my possession a bottle of Bell's Royal Reserve, 20 yo, blended scotch whiskey. It is still in the original box, with the cardboard sleeve and the bottle is unopened and unmolested in any way. I have researched enough to find that it was bottled before Arthur Bell & Sons was bought out by Guiness in '85 and was imported by Heublein Inc. so it is pre 1982, but beyond that I don't know exactly when it was bottled. My best guess is sometime in the '60s given the bottle shape and label. Please help me make some cash.
