Submarine Periscope

Picture
The British Navy generously provided a submarine periscope for use by Turkish intelligence. 
These do not become available on the open market too often, but you can check your local submarine refuse tip to see if they have any lying around. We would recommend bartering. 
So, if you have an anti-tank missile launcher gathering dust in the garage...

Make Your Own Periscope

French chemist Edme Hippolyte Marié-Davy, invented the first naval periscope in 1854, but American mechanical engineer and naval designer Simon Lake, was the first to install them for use in submarines. 
Periscopes were attached to rifles during the trench warfare of World War I and they had a variety of applications by the time the Second World War began.

A periscope is designed upon fairly simple principles. As an observation tool from below the area that you would like to view, it effectively features two mirrors at the end of a tube place at a 45 degree angle to each other. 
On the right is a Youtube video with instructions how to make your own periscope at home.
