I vaguely remember that back in the dim and distant past when I first discovered WAB I thought I might do a Spartan army. So I suspect I picked these up as part of that. They were certainly stuck to GW 20mm square bases when I retrieved them from the loft. They're from Wargames Foundry
Four of them were around 80% painted the rest were just undercoated, so it was a little challenging to find the exact paints and mimic the techniques from around fifteen years ago, but I think I got it about right.
