Check your email...I posted a reponse on this bottle to your other posting.
1) Your bottle incorporates a Plug-Cap, which was in use on House of Lords
bottles well into the mid-1960s...at which point the cap was changed to a
Screw-cap design. (See Example-1 Below)
2) Secondly, Whiteley & Co made several changes to the main label in the
1950's; including the addition of the term "100% Scotch Whiskies" in 1954,
the addition of the term "Distillers" in 1956, as well as changes to the location
of the word "Leith". (See Example-2 Below)
Your bottle's Main-label includes the term "100% Scotch Whiskies", indicating
that it was produced after 1954....and it is missing the term "Distillers", which
indicates is was produced before 1956, which is again verified by the position
of the word "Leith" at the end of manufacturers name, rather than before the
work "Scotland". (Your bottle actually dates to between 1954-1955.)
If you have any other questions, please feel free to contact me.
