Another general comment which may help others:
Here is an advert from 1954 showing a cork top Johnny Walker bottle - just because it has a cork closure does not mean it is a 19th century bottle.
The 1950s bottle was almost certainly machine made, the mold seam most likely goes all the way to the top edge of the lip, and as the illustration shows, the color of the glass appears to be clear.
Once you start examining all the details, you realize this is a different bottle than the aqua one depicted in this discussion thread.
