If the Statement:
"At full nose down (0.25 units), the top of the moving part (ballnut) is within an inch of the upper stop."
is correct, then the photographed screwjack is 80 to 90% Nose Down.
(look at the length of screwjack extending below the ballnut to the lower stop).
Whether this was how it was recovered, or if all the threads were stripped, would reduce the significance of the photo.
