The Mallory Magspark is a transformer made by Mallory that had two sides primary and one side secondary. It also had some large external capacitors available separately. "Boots" Mallory had a factory in Detroit and would run a used distributor through it for a modest fee and dyno-tune the result. Well, I got the run through and could have added vacuum advance at that time but no dynotune for me.
