Grant,

Okay here is another query. My first generation DA crank-set has an A A (one A slightly smaller than the other) on the drive-side crank arm but an S O (S larger than the O) on the other arm - the set was bought at the same time (by me) in 1977 or 1978, I can't quite remember now. Why the different codes?

Paul,
