I was on a Delta L-1011 from TPA to ATL in October 1998. I didn't think to look at the reg. number, but the reason I was wondering is it was the only time I was in the lower galley, and I got to stay on the plane for about 15 minutes, and walk around the plane, sit in the cockpit, talk to the pilot, etc.
It was DL 1672 TPA-ATL, on October 26, 1998.
Departed at 2:40pm, Arrived at 4:24pm, if that helps.
