Johnnie Walker Black, age?

[Jackalope]

Hello all, I was given a bottle of Johnnie Walker Black for a gift. A friend and I were talking about it and II showed it to him and he said it looked old. We then looked the bottle over and it does appear older then modern JW. I was wondering if anyone on here might know when this may have been bottled? This is more to settle an argument then anything else. Thank you in advance and cheers!
Okay, I can't seem to figure out the pic upload. The label says Johnnie Walker normal font and Black Label in a script font. It says 86.8 proof. Imported by Canada Dry. The lower label say By appointment of her majesty etc etc. The Foil on the cork? says Full Quart. There's a red tax label on the top, the tax numbers are175842012. The back label says Distilled and bottled in Scotland under British government supervision. Thanks again, email for pics.
