In A Nutshell Antiques and Interiors has dated this piece to the Edwardian era.

The silver bases are both hallmarked for Birmingham, 1914 and the makers Napper & Davenport.
They are in very good condition for their age. The silver bases have a few small surface marks and minor dinks but nothing detrimental and there are no cracks or damages to the glass. They have been cleaned and gently polished and are ready for use.
The best description comes from the photos so please look at them all carefully and if you have any questions just ask.
