Superb painting (as ever)! And a terrific model too. I spotted one on eBay earlier this year, along with a less illustrious orc. They were simply labelled "orcs", and I thought I might get away with buying them for three quid or so. No such luck - they eventually went for nearer £40.
I've always wondered if the Perry orcs from Hagar's companion range were in part a dry run for the 80s LotR figures. Although many of the Orc's Drift-era models share bodies or heads with the preslotta Armoured Orcs, those that don't tend to be squatter and are often armed with bows besides their melee weapons.
Hagar also raises a wave of nostalgia for the fact that he's the chief orc in the campaign but is neither outsized nor equipped with over-the-top armour and weapons. The same's true for his fellow chieftains: Magyar Ironfist, Fangor Gripe and that fellow with the Mohican crest. They're all great figures, but they're all normal-sized and relatively unobtrusive by later GW standards.
Anyway, that's astonishingly good paintwork! I love the blueish tints on the axehead and the rich browns and ochres of the tunic and trousers.
