Good find. When I was into AAs I was looking for one but never found one but talked to a guy with one in an AA. Most were over/direct/under drives with straight cut gears apparently they are quite noisy. I would trade lower revs at highway speed for some extra noise any day.
Check to see if the shifter has three positions or two then jack up the rear tires and have someone turn the tire while you look at the input shaft and shift the warford. It should give you an idea of what you have.
