This is a really lovely presentation by Morny of London. The bottle and stopper are beautifully cut and seem more like lead crystal than glass. The bottle seems quite heavy so this might actually be the case. La Valse was introduced about 1912, I'm not sure that this bottle would be quite as early but it has a small christmas gift/card calendar included in the box for Christmas 1930 so I have included it in the pre 1930 list. About 10cm or 4 inches to the top of the stopper.
The box is also very nice, covered in a paper with a linen like texture in a silver/grey colour.
