I've never seen it as a formal finish color name from anywhere but there, although it's possible it was a new name on an old formula as we've seen before. But only 3 types of 'burst out of Westerly at that time if one includes and the Cherry which was only "standard" on electrics. For that matter think the "Tobacco" was only standard on electrics, too.
All DV52's were Westerly built, see my comment above re standard color names, "Iced Tea" (as a name) doesn't appear anywhere but in Tacoma catalogs, and it's pretty darn light. Think yours will turn out to be an exceptionally light Antique Burst, that was the standard 'burst on flattops in '97.
What does your label say?
I'll betcha a buck it says "DV52-AB" (Or maybe "Ant. Burst") (Only a buck 'cause I ain't a gambling man.
)
