Circa 70 sheets, mostly 4°, also folding plates and one large folio, whiteprints, blueprints and manuscript text, drawings and charts, on different types of paper (contemporary punch holes on the left-hand side, sporadic old staining, otherwise in a good condition).
This stunning collection of original documentation by the blimp factory Zeppelin in Friedrichshafen lists all the first and last flights of the airships, marked with numbers 1-300, between circa 1900 and 1940. Added are the technical details of the ships numbered 1-129, the blue- and whiteprints for the equipment, its corrections and additions, data on the technical equipment, people involved etc.
Especially valuable technical information are those on the coverings, which could explain the cause of the fire on the airship LZ 129 Hindenburg in 1937, where 36 people lost their lives.
A large chart gives details on the first 50 flights, dated between September 1928 and November 1929.
