Yes, I flipped the wheel and it was pretty much the same crooked-ness. It's an All City Big Block. Have some pics:

One shows the skewed wheel, the other shows how it's resting (nuts undone; tension screws fully backed off; gravity holding axle against track ends).
Turning the tension screw a little on one side straightens the wheel. I know this has no bearing on performance once set up, but I was just wondering if this kind of workmanship (or lack thereof) is common/acceptable.
