Short clip of a B-17 being tested at Aberdeen Proving Grounds. The aircraft is in post 1947 markings and the film suggest it was made no later than 1952.

That's a neat little video, thank you for sharing that with all of us. I wonder why they had to hang it up like that? Why not just explode the ordinance with it setting on the ground?
