BLACK & WHITE Buchanan's Blended Scotch Whisky 86.8 Proof - 4/5 Pint Bottle

Good morning greetings,

I have an old Black & White bottle I found in the basement. It has a kork and seal cap made in Scotland, with 5 legible labels on a dark green bottle, 3 on the front, 2 on the back, one of which shows the black & white scotties.

On the bottom is embossed: "N" to the left, an "7" to the right, "S797" at the top, and "U C B" at the bottom.

Please take a look at my photos when you have a moment. Any information anyone has as to the age and/or value of this bottle is much appreciated.

Thanks kindly & have a blessed day!
