Puckerings has dated this piece to the 1870s.
It also is lucky enough to have an English design registration diamond shaped lozenge for 7th July 1876, when this design was first registered.

The ferrule too is sterling silver which attaches to the nickel framed glass which is of course new, making it very usable piece, without damage, clear and with a good magnification.
A superb, grand and impressive desk accessory in excellent condition.
