Carse Antiques has dated this piece to the 1920s.

The stopper which I think is plate but could be silver is also of a similar vine, leaves and grape design, the cork is new.
The decanter label is silver and is hallmarked for LONDON 1936 with the makers mark for HARRODS.
Please note the decanter is not as yellow as the pictures suggest.
SIZE; 13" high
