Thanks.  Very interesting observations.  I attach some pics of a Perthshire inkwell I found online.  It had very similar canes and the rounded bottom is very similar in size to mine.  I was looking at the neck and guesstimating where the neck would end and the modification made.  It kind of aligns in terms of proportions which is why I thought originally it was custom made.  Also being there is nothing like a Perthshire candle holder or / Vase / toothpick holder  (until I am proved otherwise)is why I think it is a one off maybe custom piece.

Being hollow, it was obviously blown like this. I'd suspect something experimental that was of good enough quality to put the label on and put out for sale.
But the flat rim with no decor suggests it might have had something added on top - hence my mention of cigarette lighters.
Maybe a toothpick holder?
As you may well know, Caithness sells clearly marked seconds.

It can't be a modified or altered bottle because there is no clear casing over the canes. That would be pretty much impossible to remove nicely.

thank you

8 inches tall, quite heavy and marked to the base, 1930s. There is a smaller version in 20th Century British Glass, page 134. Very pleased with this find 

  A couple of examples of very French Sandwich glass in the 'oval" hobnail pattern.

The puff box matches almost perfectly the the sugar no 43  illustrated in m's first link of pressglas-korrespondenz provided earlier in this thread. The difference according to Barlow/Kaisers sandwich guide is that the American version has a rough pontil mark inside the lid under the stem and the French version does not. They also say the French version is lighter in weight. The blue under plate in the link has 16 points and the French illustrated in pressglas-korrespondenz 14 points.

Nice to see both vases together to compare Wingedsphinx - thank you for posting. Mulling it over.  There were two pieces in Pressglas Korrespondenz, one here (seite 7 here) which showed a Saint-Louis vase with a pointed knop body,

and the other a link I provided on a previous post in this thread which showed a yellow perfume bottle with a wavy rim.
Of course neither of those characteristics are determinative on their own.  However, perhaps it shows Saint-Louis produced molds with those characteristics?

The other thing I found interesting relating to the post I've quoted here, is that I have two mid 19th (?) sugar boxes/melon boxes which I think are Bohemian.  They are exceptionally well made and neither has a pontil mark or a rough pontil mark on the inside of the lid where the stalk of the melon is applied to the lid.  Inside the lid is just a smooth slight dent at the point the stalk is applied.
