RAF escape miniature telescope.
Developed by Clayton Hutton at MI9 to aid in both evasion and escape. The escaper could use it for observing guard routines, finding wire obstacles, planning escape routes etc... and all at a safe distance. The telescope is extremely compact and it is small enough to be hidden inside a range of items. One of the strangest hiding places was inside sticks of hollow seaside (Blackpool) rock, allowing secret shipments into POW camps. These mini telescopes were made in two types, a single draw and a double draw. They were also used by the SOE and other special forces.
This example, of the single draw type, is in a very good used condition. The lenses are very clear and give a good viewing image, whilst the brass body is in a good condition.
A great piece of wartime escape and evasion equipment.
