V-12 or dual ignition six? Distributor cap

[Dan Marx]

Well as usual and not unknown to find a part that looks like one application, but could well fit another.  Attached are pix of a cap that could be a V-12 Cadillac or a dual ignition something else.  The cap has an overall dimension is approx 4.5 inches and 4.25 in diameter for the mounting rim.  Has 2 pins for positioning.  Has application for two coils and the plug wires crew in.  Any help is greatly appreciated.

Thanks

Possibly Nash 6 of the '35 -'41 range.  if so it would be Autolite IGE1003L and there would be other tractor, truck, marine and industrial applications too.

Could be for Liberty V-12 WWI aero engine.

A Nash Twin Ignition would have two terminals from the coils and 12 to the plugs. That one looks like a Lincoln Zephyr 12.

The one pictured does have 2 connections from the coils. I can tell you if it's a Nash with their double ended but offset rotor it will screw with your brain until you understand how it works. We used one on an ALF Speedster we built distributor and all. We had to reverse the rotation of the dist., not an easy task.

That looks nothing like a Zephyr cap

Oops! I lost some vision in my left eye and didn't even see that second coil terminal. Yeah, that would be a Nash. I converted one back to twin ignition that had a later distributor.

I remember the AL100 cap. Auto parts even had the rotor in stock.

 

If my eye was still good I would have caught that and not agitated that Matt Greoning thing.

It is a DR cap

Just pointing out the obvious. Not agitated in the least?

This is a Delco cap used on some v-12s and some double fire sixes (Marmon for one).  The mounting tabs and the screw in spark plug wires identify it as such.

If this is a DR cap as you say, it is the same as your other topic. Autolite made four or five in this configuration.

Autolite made a number in this configuration, all with 1003 in their number: IGE, IGJ, IGK, IGM, IGO.

(IGL 2003 is not this configuration.)

I cannot find a direct application or picture of this cap.  It is a DR cap, and does not resemble the Autolite caps.

It’s not Cadillac or Pierce. It appears to be a 1950’s Delco  set up possibly used on Seagrave fire trucks. The post war trucks used smaller diameter distributors like this cap takes, and they were dual plug 12’s for a total of 24 plugs and two distributors. They are a handful to make work correctly.  In the upper left of the photo you can see the dual drive set up and the bottom of the two distributors.
