Show us some odd ignitions from the past

MARK TEN B..
One was on my 1965 Newport "as found". The wiring was a simple add-on, most wires connecting at ignition coil as I recall. Couldn't figure if it was doing anything useful. I didn't notice a difference pushing the switch in and out, but perhaps the switch didn't work since didn't feel solid. Finally tossed it for a Crane Cams XR700 (slotted optical wheel pickup).
