Not because I didn't believe you, but for my own curiosity I looked it up.

First ever photo I could find of the kislev mounted archers was in White Dwarf #144, December, 1991.
Not advertised but featured in the very back in an Eavy Metal battle diorama.

They weren't available for purchase until White Dwarf #148, April, 1992.

Warhammer Fantasy Battles 4th edition, released with White Dwarf #154, October, 1992.

So for customers they were part of 3rd edition for about 7 months. But for the people working at GW, they were probably around for about a year.

So yes, they are technically from 3rd, but at the very absolute tail-end of that edition.
