cranks but no spark at coil

Well turns out to be the reluctor (see pic). I had another complete distributor here, so took it partially apart and cleaned and verified good. Connected dist leads to volt meter and spun the distributor. Measured approx1v ac. Also continuity test and beeped between signals while spinniing. So all good.
Getting the dist hold.down bolt in made me question my sanity.
Thanks to all, much appreciated!
