GB Millais Antiques

I have been interested in scientific instruments since my grammar school days in the 1950s then university at Guys Hospital, London, where I qualified in 1961, and then working as a Dental Surgeon, until retirement from that profession, in 2004.. My antiques business was set up 45 years ago, having followed in the footsteps of my father. Throughout this time I have dealt in scientific instruments, mainly of a military connection. This includes military instruments, microscopes, compasses, Nauticalia, Telescopes, large and small, Binoculars, especially of the German and British Naval forces of the 2nd WW, general optical items and even writing cases.

I attend the Science Fair in,London, and other Antique Fairs, especially the IACF Fairs, at Ardingly, West Sussex, The "Military Odyssey" at Detling, Kent, and occasionaly,the Bisley Fairs, and Birmingham, at the NMM.
