I started this thread in “wanted”, but I will continue it here as it makes more sense.
So, finally I have the starter working.
Thank you to Piet for his spares parts, I have to admit that is a strange feeling to open a spare item kept in his original bosch box from 50 years ago. Is a kind of privilege.
So my conclusions are. You can paint the inner part of the case, also the coil cores, and the brush plate. I just had to peel off the contact between all cases to ground the brush plate with the aluminium case and the engine. Cerakote is not affecting the magnetic fields
. So now is all protected against rust.
I had some troubles with the brushes. The first ones I got where too short and thick, so it was really hard to weld them and twist the little wire for such tight curve. I sourced another set here:

18 is a bit too long and had to lime them to 14mm but for the rest, perfect and easy to weld.
The NOS coils from Piet were just perfect, a bit time consuming to adapt them to the case so that all fits in place.
Soldering the brushes… well, recommend you a 100W welder. All other is not enough.
It is not totally assembled but enough to make the first test (see video). And spins like crazy!! The first time took 1/2 seconds before start spinning… the longest 2 seconds of my life
