The first set of Coordinates that I posted above are for the NACA 2R(1)12. I have read that the 12 denotes a maximum thickness of 12%. The maximum thickness of the early Bf109 airfoil shape was 14.2% [wing root] and 11% [wing tip] with the later versions being 14.2% [wing root] 11.35% [wing tip]. Is that correct?

The first set of coordinates were a set with better resolution and sourced from a Japanese website which also also has the following official coordinates for the 2R(1)12:

There is also some coordinates for the 2R(1)15 airfoil on page 514 of Report 572 National Advisory Committee for Aeronautics (figure 17). Could someone explain the formula for getting the correct coordinates for:

NACA 2R1 14.2
NACA 2R1 11
NACA 2R1 11.35

Any help is appreciated.
