From a post over at Stud.io, the six centre pinholes are rotated by 90 dregrees.
So the correct code for the interior is
1 16 0 0 0 0 1 0 -1 0 0 0 0 1 s\57519s02.dat
1 16 0 0 0 .866 .5 0 -.5 .866 0 0 0 1 s\57519s02.dat
1 16 0 0 0 .866 -.5 0 .5 .866 0 0 0 1 s\57519s02.dat
1 16 0 0 0 0 -1 0 1 0 0 0 0 1 s\57519s02.dat
1 16 0 0 0 -.866 -.5 0 .5 -.866 0 0 0 1 s\57519s02.dat
1 16 0 0 0 -.866 .5 0 -.5 -.866 0 0 0 1 s\57519s02.dat
What should we do with it? Create a "b" file?
The original file might have pins or axles in place that won't fit any longer if we change it.

If I am not utterly wrong, you get the same result with a 90° rotation of the whole wheel

That’s what I thought at first as well, but if the pin holes are aligned with the axle hole, they point to a gap, but they should point to a tooth.

Oomph, you're right... Not sure it's worth correcting it, but if we do, then I'm afraid a "b" part is mandatory.

Why is that, I always thought 'b' ones are only intended for mold differences not mistake corrections. Otherwise the library would hold more corrections then real parts.

Most corrections don't warrant a variant. However, in this case since the orientation of function elements of the part will change, this would "break" the part for those model that already use it and so needs a variant.
