Is the .4mm of runout reported by diss7 enough to cause these issues? I don't know.

You have to remember, that the 0.4mm on the a ~25mm hub would then be 3x as bad on a ~70mm pulley
You can see what it looks like in the video I linked to in my build thread. You don't want the pulley 0.1mm on the piss, let alone 1.5mm.
Re serial numbers, posted pics of both up.
