Spy these binoculars rescued from HMS Invincible.
The binoculars originally came from HMS Invincible (1907), which was sunk at the battle of Jutland in 1916. They were subsequently recovered by a Norwegian fishing vessel.
These prismatic binoculars have a leather-covered body with loops for a carrying strap.
The eyepieces are made of bakelite and focus independently. The maker's name appears on the body, as does the government broad arrow mark and the magnification of the binoculars (6), as well as a testing mark from Kew Observatory.
