A couple of people have asked (offlist) whether these problem cranks are marked as pista (theorizing, I suspect, that they're a crossover or front crankset made for a tandem).
Answer: Yes, they are stamped 172.5 PISTA.
Did Campy make drivetrain components for track tandems? There must be a simpler answer.
I found another drive-side crank to use for now, for this build, but now I have two different length cranks on the puppy. Does anyone have a non-drive 177.5 SR or NR crankarm they want to get rid of? Pista or Strada would work.

Two left feet?
Ok, so I'm building up a fixed gear, and I have a Campagnolo Pista crankset I want to use. It's a 144BCD crank with 9/16 x 20F stamped at the pedal hole, but it also has a large "S" near the pedal hole. This thing has reverse pedal threads on the drive side!
What's the story here? None of my other cranks are like this. How do I deal with this puppy? Do I have to thieve a left-hand spindle and put a right-side body on it? Why the heck is this crank the way it is?
Anybody have a spare left-hand pedal spindle laying around for a Campy Pista pedal? How about a left-hand pedal spindle for a Dura-Ace 7400 Pista?
I was so smoothly spiraling in to completion of this bike. Grrr.
Cheers,
