A 1914 dated brass naval "gunsighting" by W Ottway & Co Ltd, Ealing ..... this is all etched / engraved into the brass

Type V.P 3-9

I assume it mounted onto a tripod of some description, if this was supplied with the gun sight, it is no longer with it.

In original box, box is complete but with external wear, however with original latches and key.

Overall size of box approx 73cms x 15cms

A quality piece of British optics and engineering
