Hello Art,
Distillate and Persuaders both have AXYs only (humcanceling), unless they were custom ordered with series electronics, in which case you 'd see a hum canceler in the middle.
The shape of the single coils and the AXYs is the same, so they are hard to tell apart in pictures. The single coils are much heavier then the AXYs, though, so if you had one of each in your hands you could tell them apart form the weight.
There is no electronic difference between bridge and neck pickup; generally the lead on the neck pickup is a bit longer, but that's it.
