White Horse bottle
Feb 1754 is the date of founding of the blend/brand, not the age of the bottle.
The gentleman who supplied the picture has a mid 20th century bottle. I have two bottles that date from the 1910s including one that has the original outer wrapper used in packing/shipping. The label on the bottle underneath is in perfect condition. Both bottles predate White Horse's use of the Stilton cap (screwtop) which came in the 20s/30s.
