I picked these today.
Scintilla looks like it's a dual 4 cylinder but I may be wrong
Mea also looks like dual 6
By picked I mean bought. Ill try to post better photos later on.
Not much. This "Smokstak" discussion looks like the Scintilla:
The Bosch looks like my regular Bosches. The switches do look like Duplex. I'm not sure what the Duplex differences are:
The bosch says Du4 Duplex on the base.
The scintilla has me stumped. It has 8 terminals but the model number is PN5-D. Almost every scintilla magneto I found online was in reference to Bugatti or Lagonda. That's hard to believe.
Correction. The scintilla magneto is indeed a 5 cylinder mag. The Mea is a six cylinder.
Looks like I struck out. I hope you find the answers.
Thank you for your help!
