Vespa 50 L stator plate

Hello Everybody,

I'm currently rebuilding my Vespa 50L (1967) and I have problem with collecting particular parts to rebuild the stator plate with internal ignition coil. I can't figure out which ignition coil and also which and how many support coils should there be inside. The problem is that the former owner who hadn't have parts dedicated for Vespa decided once to use everything what was avialable in Poland in early 80ies. And now everything inside is complete electricall mess. Could you please point which parts should I buy.

Sorry for bothering and thanks in advance for answer, especially that I realize the question may seem stupid (how can I possibly rebuild the oldie if i do not know which coils should I build in on the plate).

Cheers,

Lukisz
