I have a bottle of Black & White with numbers on the bottom of the bottle: n8125 -n5 -ug8. The label says: Product of Scotland... Black & White (no dogs).... Special Blend of Buchanan's Choice Old Scotch Whisky ......James Buchanaen & Co Limited.....Scotch Whisky Distillers...Glasgo & London...Glentauchers Distillery, Mulben (may not be and as the letter seems to have been rubbed somewhat over the years) Speyside. The bottle is dark green with Black and White scotch Whisky engraved in the glass and has wire on the cap with a heavy white shrink label. Does anyone know the age and value or where I may find the answer?
