Puckerings has dated this piece to the 1890s.
The silver ferrule is where the hallmark for Birmingham 1899 can be found.

The magnifier itself is of course newer (by Hilkinson), making it quite usable today with a clear lens and good magnification, a couple of wear scratches to glass surface, mentioned for accuracy only.
A good large size measuring 7 1/4" in length, the glass having a diameter of 3".
