This is a very pretty, relatively small decanter.  I have eight (including two glass items) decanters hanging around.  No…they are not all full (only two of them are in actual use).  I bought this one in the U.S I think.  I am guessing that it is of a good age and wouldn’t surprise me to find that it is European.  I love the engraving on the stopper.  I’ve not seen that before.  The problem – when washed, because of the very narrow neck, water dries in the bottle and then leaves  marks inside the bottle that are visible when empty.  I read somewhere that you should dry your decanters with a hair blower in order to avoid these marks.  I tried this, but almost burned my hands!  Took too long and didn’t work.  I guess I could fill it!  I don’t use this one as I don’t want the stopper to become damaged.  It is pristine to date.  I came across a reference to a book about  identifying old British decanters.  I may have to order to see if this one shows up.  There is something very James Bondish about pouring wine, or brandy, from a decanter.
