Bosch D6 dual Spark

[Blunderbuss]

Hello, I’ve got “most” of a D6 dual spark. I’m just curious if anyone out there has an extra armature hanging around, or the bakelight distributor Caps. Or if someone has a 4 cylinder dual spark magneto, and needs this. I’d entertain a trade if some sort.

I am no expert. But a D6 is different than a DU6. I had an incomplete but hot DU6 many years ago. I gave it to a friend that had a couple cars that used six cylinder Bosch magnetos in case he might need the parts.

While I expect a few parts may interchange? Overall, the two series are quite different.

You’re correct, I need D6 parts.  I was mistaken.

So you are looking for cap that used 12 wires for 6 pairs of spark plugs?

Looks like you are missing the electrode that goes from one of those two terminals to the front of the magneto.

DU4 should be the same except the cam and cover would be for 4 wire/sparks
