    Can anyone explain this distributor cap...I would really like to see the rotor? 5A21F477-4065-4A5F-8054-ABB562365CDF.jpeg

    Looks to me like a hot Wayne 6 cylinder with dual spark plugs, 12 lugs on the cap, and a few spark plug wires not installed.

    I don't know, never saw one with dual plugs. But are there not 6 pairs of lugs on the distributor cap? 12 total?

    that is a piece arrow distributor. It was a common hot rod practice to put those on engines with 2 plugs per cylinder. It is similar to the aftermarket W&H dual coil distributors that were made in the fifties and sixties. there is a spring loaded brush on the rotor that picks up the second coil from the ring inside, see the pic dualcoil.jpg

    they are probably running one plug per cylinder but using the dist as a dual coil unit. It gives more coil saturation time and thus hotter spark

    Could it be that there are 6 spark plugs, and each pair of spark plug wires fires each spark plug twice? Actually, maybe an extended single spark.

    I understand the arrangement of the plug wire spacing on the wires around the perimeter of the cap, so, I am assuming the 2 "inboard" wires go to coils? Interested to see a view of the internals without the cap...my flathead has a gennie, crab style distributor that has the strangest rotor i've ever seen, but this one has we scratch'n my head.

    I missed the part about saturation time with a single plug per cylinder, now I get it.

    For those who’s wondering , the distributor is a very early spalding made for the Wayne F Horning company for the Wayne 12 ports back in the early 50s ,
    its a Nash twin-plug distributor cap , with a modified base to fit on a Chevy distributor , every other lobe is grounded off the shaft . it provide 2 distinct 3 cylinder coil circuits . . . doubling dwell time and maximizing coil saturation at high RPM.
    , it’s a very Frankenstein setup but works very well and it was a hotter spark than a mag in the early 50s ,

    also the crazy part of this whole setup is if you switch the coil wires around , it puts the motor 180 out .

  25. At the age of 14 ( 1967 ) in Australia my very first vintage car was a free 6 cylinder 1928 NASH . Real big car and i had no idea what i was doing except dismantling . ( learning curve ) The 12 sparkplugs and that big distributor cap where interesting. I remember lifting the cap and there was a extra new cap stuck under it . The automatic chassis lubricating system was interesting as well. Sold the whole car in pieces for $ 50. Anyhow when i moved to The Netherlands in 1978 i took the new cap with me. Sold it years later for good money.

    Add me to that list of folks who say thanks. That's quite a setup. Not far off some of the dual point V8 distributors with 4 lobes on the distributor cam though.
