I have finally painted half a dozen pack mules (and ponies) that I thought I'd bought a couple of years ago. Turns out it was 2011..
Three are from a Warlord Games ECW pack and the other three have been converted from TAG Cossack ponies which I declared too small to look right for wargaming (although I appreciate they may be technically accurate!) To keep things simple I just stuck some spare blanket rolls on them which came from the Perry plastic AWI British infantry box.
It always feels good getting bits and pieces like this done, so next time I need a supply convoy for a game, I'll be able to dig these out :)
