History
NA-62 was North American's internal designation for the first production contract, which produced the first 24 unsuffixed B-25s. The first nine kept the NA-40's constant wing dihedral; after directional-stability problems appeared, the remaining fifteen received a gull-shaped dihedral break in the inner wing, a fix retained through the rest of the family.
