The crank should be a Shimano 600 with half-step gearing. The Sugino is a downgrade, but you might like the "normal" triple better.

I'm not sure I really even understand what half-step gearing is. I'm sure I have a normal triple now 52-42-30, on my Jamis. I live in the flatlands, is half-step gearing more for mountains? The Trek is from the flatlands too, so maybe that's why it got swapped to a normal triple?
