Anyone Know What Decade These Are From?

I went digging through my Grandma's liquor cabinet tonight.

I found a bottle of JW Black and Old Parr both in boxes and unopened. I looked for the obvious markings, but could not determine how old these bottles were. My Grandpa drank whiskey and he passed about 30 years ago, so, I'm thinking they're at least that old, any way to get a more precise year?

"295322" was on the bottom of the OP box
"AQ/CP A484" was on the bottom of the JW eso box
