10 x 7.5 inches. A magnificently illustrated report (31 photographs, numerous plans, some folding) on the German WW2 Junkers KM8 torpedo engine. This engine is of particular note in that its revolutionary rotary disc-valve assembly was designed by Felix Wankel, later of rotary engine fame.
In pristine condition in original buff-coloured wrappers. Marked as "Copy No. 230". Protected in a modern handmade archival cloth slipcase, leather label titled in gilt.
A copy of this same work is in the State Technical Library in Prague.
Following the Normandy landings in 1944, American and British intelligence units (BIOS, CIOS, JIOA) working under SHAEF (Supreme Headquarters Allied European Forces) produced a wide-ranging series of surveys and reports on captured German industry and armament production as allied troops advanced across occupied Europe. Printed in small numbers for a restricted circulation, these military and commercial intelligence reports, containing material unpublished elsewhere, seldom come onto the market.
