I think the only others are the Half-Orc hero from the C33 mounted adventurers range and the wonderfully named Half-Orc of Grim Countenance from the Fantasy Adventurers (on foot) and FAC (mounted) ranges
Saw him listed on ebay, but tbh, a few of that guy's minis looked very badly worn/rotted.
And after getting burned on a load of pre-slotta dark elves last year that literally crumbled when i picked them up out of the box, I'm a bit wary of alot of pre-slotta auctions now
Which is a shame as there are so many wonderful ranges from back then I'd love to have.
