** An outstandingly rare WW2 Restricted military intelligence report, every distributed copy with its own unique security number, this being 'Copy No. 478'.
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.
