That's odd. I'd pretty much ruled out 1982 in my previous post because the main colors offered for the 610 frame were pewter, gunmetal, and red. I didn't think any of those would show up particularly blue, but I suppose it depends on Trek's interpretation and/or whether the guy who mixed the paint was listening to "Mr. Blue" at the time.
