dpast32, welcome to TFL ! .
Outside of Winchester, there's no SN listing for the later AE models, mostly because there's little collector interest in them, unless they're the first/last of whatever change.
The CBS (crossbolt safety) was instituted in 1992 at approx SN 6,000,000, and discontinued in favor of the tang safety around SN 6,450,000 in 2003.
Ergo, my WAG is that your .44 Trapper dates from about 1998.
