Please
note:
I ship to USA
only.
Also
, depending on the buyer's location, eBay may collect state sales tax for this item.
For sale
is
a copy (NOT an original) of a vintage blueprint of the RB-49A
flying wing bomber entitled:
"
Diagram Wing Structure"
and hand-dated:
6/22/48.
The drawing is marked:
"LOWER SURFACE".
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.
"CONFIDENTIAL" is crossed out on the original and the date
is hand-written on it, and there is an age-yellowed crease which is replicated in the copy.
Condition is good.
Please see
the photos.
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 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.
