If you've never opened that BB, it could be that you have pitting on the spindle races...not at all uncommon. But yeah, the cup does look cockeyed. Could be the threading on the BB shell is off center. One advantage to cup and cone BB assemblies is that they do tolerate some degree of misalignment.
I figured that misalignment might be causing the binding, the bearings feel fine otherwise, no crunchiness or anything, it spins nice and smooth till the drive side pedal hits the 12 o'clock position and then it gets tight.
My main wonder was whether or not I'd need special tools to work on it because of oddball threading or suchlike.
