308 starter motor ( Fiat ) pics needed for rebuild

Hello from Germany,

when in 1997 the Fiat starter on my 308 GTB died, I purchased a new Bosch replacement and went ahead.
After that I tore it apart - a big mistake - threw the parts into a box and forgot about them, because I never believed, that I will ever get that part which has broken. The pinion drive assembly.
But coincidentally a few weeks ago I really found new solenoids and pinion drives ( cheap ) for this Fiat starter and now I would like to rebuild my old Fiat starter.

Because - like mentioned above - I stupidly tore the starter apart, I would need some detail photos of the internals.
Did someone of you dismantle that starter and take any photos ?
Or is there an exploded view drawing somewhere out there ?
Any help would be highly appreciated.

Best Regards and thank you in advance

Martin
