The spindle does not appear damaged. The cotter pins appear identical so I don't believe they are the problem. The holes in the cranks that the cotter pins fit through do not appear particularly worn and neither crank is bent. I'm wondering if the faces on the spindle where the cotter pins seat were not ground properly when it was made.

I have ridden it and It IS rideable. In fact, one hardly notices the slight crank misalignment when pedaling. It's not a valuable machine; it just neatly fills a space in my small collection so perhaps I shouldn't bother....It just 'bugs me' knowing that it's not quite right.

Only a guess, but a fairly common mistake with cotter pins. Properly installed cotter pins enter both cranks symmetrically. If each crank is pointed rearward, then the pin enters the hole from the top with the nut at the bottom. Viewing both cranks from the side, the pins will enter from opposite directions.

Hope this isn't too confusing.
