Thanks, guys.
I was wrong -2005 was the repaint, not 2007. I'm getting old. Two of my four RAGBRAI bands are still on the stem (06, 08, 09, and 10).
She's a 2003 Trek 2300 --the last all-aluminum (except for the fork, which was the OCLV 110 fork like the Trek 5200) pro-level made-in-USA model before they shifted aluminum bikes to overseas and added carbon stays. Trek did a bad decal job, didn't even clear-coat, and they started coming off a year later, so I did what I wanted to do in the first place. They used Klein's aluminum alloys from when they bought them out. Eleven years later, she's still a great ride, albeit with 100% different parts.
