** An outstandingly rare WW2 Restricted military intelligence report, every distributed copy with its own unique security number, this being 'Copy No 346'.
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.

44 pages, 14 photographs & figures, other illustrations.
Very good in original stapled card wrappers. Protected in a modern clear archival jacket.
Because of the sensitivity of the material this report contained, it was quickly suppressed, and not subsequently issued in unclassified form.
One of the rarest of the CIOS reports.
