** An outstandingly rare WW2 Confidential military intelligence report, every distributed copy with its own unique security number, this being 'Copy No. 178'.
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.

A slight report but by a notable automobile engineer - a good example of his painstaking work.
Wunibald Kamm (1893-1966) was an automobile designer and engineer, rightly famed for his pioneering work in aerodynamics, driving dynamics, tyre technology, minimalist construction techniques and engine combustion efficiency.
He is best known for his breakthrough in reducing car turbulence at high speeds; the style of car bodywork based on his research has come to be known as a Kammback or a Kamm-tail.
Dr. Kamm went to the United States as one of the first hundred German scientists stationed at the Dayton, Ohio Wright-Patterson Air Force Base and remained there as a consulting engineer until 1953.
