B-17 Flying Fortress B-17 Wreckage Part: Bomb bay door stiffener

Green stiffener from the left or right bomb bay door of a B-17. It was installed on both, and the part number 75-4122 remained unchanged. It is visibly bent, which makes it difficult to determine the original length. According to the blueprints, the part is 10.44 inches (26.52 cm) long. Three of these stiffeners were installed on each bomb bay door.

The part number 75-4122 is visible. Additionally, the digits '606' are engraved. This number indicates that it was installed on the right door. The number '376' is found in another location; its meaning remains unclear.
