** An outstandingly rare WW2 Restricted military intelligence report, every distributed copy with its own unique security number, this being 'Copy No. 288'.
Very few examples of this classified and security-numbered report have survived. Because of the report's extreme rarity, few collectors know these documents exist; only a tiny handful actually owns one.
An 'ordinary' version of this restricted CIOS intelligence report was subsequently authorised for issue. The later version was given the same title but had the HMSO name as publisher on the front cover and lacked the security classification and unique identifying security numbering.

The Natter was one of Hitler's secret weapons that, although built and subjected to gliding and unmanned power flights, never saw action. Its sole piloted powered test flight resulted in the death of the pilot.
The intention was for the pilot to close with the target aircraft before jettisoning the nose-cone and firing 24 Henschel Hs 217 Fohn unguided rockets. The pilot would then turn away and parachute to safety.
