Puckerings has dated this piece to the 1880s.

The brass bridge is signed H.H. & Son, Liverpool and struck "No.23759" which I take to mean the design registration number for the year 1885.
Excellent condition measuring 5" wide x 4 3/4" tall extending to 6 1/8". The case measures 6" tall x 6" wide. The optics are in perfect working order.
