I have a very old Black & White whisky bottle. The front and back labels are not so good. It was found in an old warehouse in 1969 (termites started eating the labels). There is a code at the bottom of the bottle: NB12 S, big L in the middle, 4 below the big L. The picture attached is not too clear. It is unopened and still sealed. How old is this bottle? Any idea how much it is?

Thank you.
