I have always maintained even way before flight simming became popular that the above were flap settings for the BAC 1-11 500 series.
Some fellow aviation fans, even those who flew professionally & commercially, insisted on either fewer or more than what I mentioned above.
Not being a pilot I did not want to argue nor to insist on the 6 flap settings evidenced by this photo that I took & have quietly kept.
However, please feel free to comment &/or correct me if I am wrong.

This photo shows flaps at 45° degrees as we approached Manila (MNL) for landing.
The image is purposely not leveled to show as much of the wing as possible.
