    For sale
    is
    a copy (NOT an original) of a vintage blueprint of the RB-49A
    flying wing bomber entitled (in part):
    "MASTER lines and stations".
    It is drawing number 70001 and it was page 1 of 4 according to the title block.
    Only page 1
    is present.
    Much of the title block and other info is unreadable as the print is a reduction of a much larger original.
    This is an interesting drawing as it provides basis for the airframe coordinate system (stations
    and water lines).
    It appears
    that Mr. Le Vau may marked up the
    drawing
    to highlight bulkheads.
    The original copy of this item was contained in a collection of Northrop materials owned by career Northrop
    structural engineer
    (
    Lawrence Le Vau)
    from whose
    estate these materials
    came.
    The drawing is marked up in color to highlight bulkheads and
    the number 1012 is hand written in red pencil but the print is in otherwise good condition (again, for sale is a copy of the
    print).
    Mr. Le Vau worked on the B-35 and the B-49 flying wings and it appears, based on the materials provided,
    he worked
    on
    the F-89D Scorpion as well.
    He was on a team that investigated the crash of YB-49 aircraft 2.
    It is likely that Mr. Le Vau
    referenced and marked up this print while working on the crash investigation.
    With
    the original
    item
    being an actual blueprint
    I was concerned about the legality of selling it.
    I was told
    by
    Maxwell AFB
    personnel that since the item is over 50 years old it is fair game
    .
    This item would
    be of
    particular interest
    to any fan of the history of the Northrop
    Flying
    wing
    aircraft
    but would also be
    of interest to any military aviation buff in general.
    Any folks involved in the design and manufacture of military aircraft
    might be interested in this as well.
    Please
    ask any questions you might have prior to bidding
    .
    Thank you.
