Periscope No 9 Mk II
Description
Periscope No 9 Mk II used as a trench observation device. The periscope is made from wood, is rectangular in shape and is held together by nails and metal straps. There are two glass mirrors placed at 45 degrees inside the periscope. The periscope is painted olive drab. In the centre of the back of the periscope are hinges, with a latch at the front. This is to allow the periscope to be folded down. There is a metal border around the bottom edge of the top half of the periscope. At the bottom observation end is a steel stake that can be folded behind the periscope. It is attached to the periscope by a wing nut to secure the periscope into the side of the trench. Above the observation mirror is a paper maker's label with the following text 'PERISCOPE No. 9 MK II / (22 1/2 inches between Mirrors) / ADAMS & CO / 1917' and user instructions.
