Well........For starters, the 90's repros were made and marked by Miroku, while the earlier, originals were made & marked "Winchester" only - and, yes, some were factory engraved on special order through the Winchester Custom Shop of the day.
IIRC, the later Hi-Grade Browning/Winchester repros (all models) made by Miroku copied original Winchester engraving patterns - so, as long as the buyer knows exactly what a genuine Winchester engraving pattern looks like, they're golden, when checking out an engraved oldie.
