No to most, but I can do a ZA2.
That said, I'm about to pass a pile of Douglas magneto stuff (E.I.C., Bosch Arc Light, Bosch ZA2, B.T.H. M2 racing, etc.) on to a person who restores magnetos. If you drop me an email - use the "envelope" icon - I will put you in touch: it may be better for you to buy a fully reconditioned magneto ready to fit to the bike.
Ditto for other magnetos. D-day is Friday.
